@somoya, your accusation doesn't has any proofs or evidence, so we can't say your accusation is legit. There was an accusation about OP, but since it was lack of solid proofs, DT member were opposed the flag https://bitcointalk.org/index.php?action=trust;flag=2459

But personally (IMO), having all of sales thread in self-moderated isn't trustworthy (if you feel someone spamming in your thread, you can simply report their post to moderator without using self moderated).
