I have no idea why Yobit sets their maximum so high. All a 20 post maximum per day does is encourage people to post crap. As for people that actually join this campaign, I will not personally give them red trust. However, if they start spamming the forum, I will use the report to moderator button.
If they can pick some good posters that can join in their campaign then it will be a different situation for them but its not. They will just accept anybody so even the worst spammers in the forum can join in this stupid campaign. I'm not here when the Yobit scandal happened here but because of that, the reputation of the exchange has been changed. To be honest, the exchange itself is not attractive for me.
If they want their reputation to be back, they must do something good

They create a lot of scam coins, exist only in his exchange. Created only to take money from people, nothing more. Can we expect something better from there, and that it will not tolerate spammers in his campaign?
If they want their reputation back, they need first to delist or update all altcoin wallet on his platform. They need to stop creating trash like Limbo, Lambo, Yo, Yozi, Liza, Lizun, Yobix ...
