We've been having a sock-puppet attack on the GameDev Stack Exchange site over the last few days. I am not fully aware of the details but there seem to be two exploits being used:
First - the threshold for flagging comments and having them auto-delete seems to be way too low. With enough account...
@Eric In case you missed it, the same user was involved in another meta post around the same time here. The above one is more relevant here though since it's an exploit which is just as possible here as on GameDev.
Both are pretty exploitable, but considering we have ~1,000 questions it's reasonable for us to recognize duplicates more easily than on a site with millions.
If this happens, we should buy stack.moe and have it redirect here (not sure if that's legal/ethical/whatever). It's 9 characters vs 23 for the current URL.
