I was not one of the three users (two moderators) who cast or processed flags on your answer.
However, as a moderator I can confirm that these actions happened, as you can see below:
Ordinary user cast a spam flag
Moderator 1 declined the spam flag
Moderator 2 cast a spam flag (which deleted your answer, and presumably led to the 100 point deduction)
Please do not ask for more details as an answer because that area is reserved for direct answers to the question.
The 50 point reputation requirement is there for the reasons discussed in Why do I need 50 reputation to comment? What can I do instead? so I recommend reading that Q&A and following the advice in its only, and highly upvoted, answer.
This seems to happen if a user's answer is first accepted (+15) but then the acceptance is removed again (-15 => total 0).
I think this makes sense since it can turn out that the answer is wrong after all or that there is a better solution which should be accepted.
Although the motivation of this request is good, I am concerned about unintentional bad consequences. On plenty of sites a few people come along and build relatively large reputations quickly either through posting a great many questions or a great many mediocre answers. In neither case should the accumulation of reputation allow them unilaterally to post ...
At the moment you have 3 upvotes and 1 downvote (net 2 upvotes).
I assume that when you checked, you received 8 rep because at that moment you had 1 upvote and 1 downvote. Sometimes it takes a while for the system to update :)
Reputation is given to its users by the Stack Exchange network based on their interactions on its sites so I would not expect to see any request to have someone not already interacting with us awarded such a bonus succeed.
I think the best option to help anyone who would appear to be a worthy recipient of such a bonus is to make them aware of Why do I need ...
It seems to be related to the same event as is being asked about at Meta SE in
Massive user removal in one night?
As @Animuson has answered there:
One or more users deleted their profiles, and there's really not
anything further we can discuss about the topic for privacy reasons.
I think the decision on whether to retain reputation on (self-)deletion ...
If this is reproducible then I would say that it is certainly a bug, but it sounds like the evidence is somewhat anecdotal.
I make a lot of Comments, and have often seen the Qs & As that they are on deleted, but I have never observed nor suspected deleterious reputation changes like those you describe.
I'm reproducing the full dot point from the SE ...
Although my initial thought below the line may apply to symptoms similar to what you observed, the actual reason is that you recently passed 500 approved edits.
You can see at https://gis.stackexchange.com/users/112447/lambertj?tab=activity&sort=suggestions that you have made 530 suggestions with a few being rejected and a number on posts that were ...
Over time I have become less and less comfortable with using this Q&A as the place to add suggestions for new tag synonyms because the more there are here, the more likely they are to get buried, rather than assessed and implemented (where appropriate)
Consequently, I would like to encourage anyone reading this answer, to vote for a change in how tag ...
The answer should be written as an answer imho. So 1. is not really an option, I'd say.
I would add another answer (2.) if my contribution to the answer is more than adopt one or two lines of code or change some variable names. In the case you linked, the owner of the question could have posted the code in a separate answer and it would have made sense.
Who would select the "deserving questions"?? (I know I'm not qualified!) To find good questions, sort by votes on our main page and look for those without accepted answers (or with no replies at all).
Users with even a little bit of reputation can give it away in 50 point chunks as they wish. There are some creative uses of this. For instance, some ...
Yesterday I noticed we have:
mapping x53 "The act or process of making a map."
cartography x520 "The study and practice of making maps." (with 'map' as a synonym)
The use of 'mapping' appears to be all over the... board! (pun avoided), however per the description I would say it should be made synonym of cartography.
I could also see making a revision to ...
stereo had four questions and no Wiki, and stereo-compilation one question and a Wiki.
I was just going to edit the tags to eliminate stereo, but I did the first one and realized I'd mentally reversed or confused the counts (thought compilation had more). It was an improperly split tag anyway (stereo and compilation as two tags), so the edit I did was valid....
assisted-gps (8 questions) seems more clear and SE consistent than agps (2 questions).
erdas (the wiki of which even says and refers to imagine) and erdas-imagine Perhaps when one was the company and the other a specific software suite, but now? If both are kept it seems some wiki cleanup/distinction is in order.
gdalogr currently has two questions associated with it:
Can rgdal use an external GDAL installation?
Custome QGIS application with WPS and GDAL/OGR
The tag in these cases is used to refer to the GDAL/OGR suite. However in most other cases on the site questions referring to the GDAL/OGR suite these type of questions are usually referred to with just gdal or ...
Besides what PolyGeo has already said my advice to gain initial 50 points of reputation is to help curating the site by suggesting improvements on questions and answers through editing. Each edit suggestion that gets approved is worth +2 points (then, you need 25 successful suggestions which is not too much).
One advantage of such approach is that it helps ...
Not sure if there is an official/correct answer for this question, but here are some arguments that might help explaining it:
The fact in which Community Wiki (CW) content usually is opinion-based makes reputation not so relevant under a "validity" point of view. For example: What makes a map beautiful? is very subjective and visual. No reputation is ...
Tips for how to quickly acquire the 50 points of reputation necessary for the comment everywhere privilege can be found at Asking for clarifications with less than 50 reputation points?
However, when you say that you would:

The cited answer is one to which I applied the post notice and, in its current one line state, I think it should be left there.
I almost always process the system generated flags on one-line answers by applying a post notice, irrespective of who the poster is, so that it is the answer, rather than its poster, that is being assessed.
The exception is ...

It is great that you are thinking about how the site works, and how it may work better. While your idea sounds appealing at first, I think there are two strikes against it:
