User Didntstormarea51 (https://salesforce.stackexchange.com/users/71040/didntstormarea51) just posted 3 answers to questions that were a few years old in the past 5 hours. This by itself is not too fishy.
The fishy part comes in that on each of those answers, he now has +6 or +7 upvotes on them. I repeat this is in a five hour span and on ancient posts. Certainly not any post that was remotely active and the answers were not even that great to warrant the huge swarm of upvotes. Also, each of the other answers appear to have been downvoted on heavily (including one of mine, which is how I noticed this).
I was not sure where to go with this so thought I would check here and see if I am being crazy or if this should be pushed to someone to try and investigate?
