You call people a shitposter because their mother tongue isn't in English, no one doesn't have to speak perfect English.
I bet if I joined a campaign that only paid for posts in the Russian section, I'd get mocked and ridiculed for it--and I'd deserve it. People who can't make themselves understood and who have nothing to say shouldn't be posting in the English section.
Many people who don't have enough incomes can earn BTC thanks to bounty campaigns.
Many people don't give a shit about this fact. If the forum suffers because of it, the parasite is basically killing the host.
1 in 4 is utterly ridiculous.
That's a big WOW for me, too. On the other hand, given Yobit's standards I'm not shocked that it happened and happened so quickly. It is a bit jarring to see so much spam after a respite period the merit system provided.
I have the Bitcoin/Altcoin Discussion sections on ignore, and that helps. The Yobit spam brigade has infiltrated Economics, though. That's a pain in the ass, especially when I'm looking for posts to merit.
