There was an answer to this question that was blaitent advertizing, and as many other people, I downvoted it and flagged it.
When this 'answer' is deleted will the rep from the downvotes be restored? Are we meant to downvote these answers?
Downvotes on questions no longer cost the casting user 1 reputation, so they are effectively “free”.
Downvoting these answers is certainly a good idea to make sure they stay at the bottom until we (the moderators) get a chance to see the flag and delete the answer. Whether you downvote or not, make sure to flag it so that we are made aware of it.
