Manipulation? You can't ignore the fact that SMAS has such a major positive impact on the forum due to a lot spammers have been stopped and forced to improve themselves in order to get unbanned.

Instead of complaining and looking at what others do, try your best to improve the quality of your post where you can ask for an account review by the managers behind SMAS. And who knows, you may get unbanned.

I already see that (previously) notorious spammers are doing their best to up the quality of their posts. Bitmixer was a campaign that had so many people spamming the forum, that Lauda took over and cleaned everything thoroughly.

If you look right now, then the majority of the spammers come from secondstrade and qtum. But then again, qtum accepts even SMAS blacklisted users, so in that matter, these users spamming is no surprise at all.
