Hello wickedfire community,
I am one of the anti-spam volunteers that patrol 4chan.org and I came across this thread after it was posted in one of the epcash spam posts on 4chan.org. I have come here to inform you on what is going on over there.
For about a year and a half, 4chan has come under attack by one spammer in particular who goes by the alias of "Chris Beer." He started with sharecash and has since moved through other CPA, CPM and pay-per-click services such as CPALead, neverblue, perfecttracking, ecastig, dengee and a long list of other such companies (I'm sure you're familiar with them).
The spam post you're talking about is being "bumped" by a bot, the community for the most part is not falling for it. There are some new users and stupid people that don't understand it's spam but most users simply skip over it and don't much care. Also, there isn't a general backlash against the spammer(s) because the community doesn't seem to care (big bad /b/ isn't as powerful as you think, unless they want to be). This spammer is not making much, if any, money due to the dedicated volunteers combing 4chan's many boards for spam. In this case, epcash is being spammed by the domain owner and he is profiting off of users filling out surveys powered by dankcash and neverblue. An unsuspecting user thinks that doing the surveys and gaining the points will mean rewards but that is not the case.
Sadly, this is nothing new. A clone site run by presumably the same spammer(s) is located at voucherbounty.com as well. They are pulling the same spam posts and same replies via bots. This is just another site in a very long line of spam that has been going on for too long.
I would like to end this post asking users of this community to not advertise anything on 4chan.org. I do not wish to make enemies but anyone spamming on 4chan can expect to have their earnings revoked and accounts banned from the respective companies. I should hope, though, that there will be no problems in the future.
tl;dr: Spammers suck, so does epcash.
