Reposting is not a problem, it’s an NSFW server, nobody will downvote repeated content. What was getting down voted were dudes and chubby women showing off.
I cannot affirm with certainty there is correlation, but the main page is far more diverse in people and content since the removal of the downvote, and constant reposting is not a thing I see (at least for now).
Really gonna do my guy Megamind dirty like this?
