I recently failed a First-Post review audit because I "Improperly" wanted to downvote (and then flag as spam) the following answer:
While the post may answer the question. The user is also (pretty blatantly) asking for bitcoin donations. They even mention in the comments that this is their real bitcoin address.
I don't understand why, but the answer is highly upvoted, which is probably the reason it got put into the audit queue. I still stand by the fact that I think it's spam. Please correct me so I don't fail more audits like this.
