I learned it the hard way as I was one of the members who participated in that giveaway thread and got a 7 days temp-ban. Thankfully, three or four days later theymos stepped in and lifted the ban since many active and reputable members were affected.
I believe you implied about the events hosted by Bitcasino.io team in the past.
This is one of the reasons why casinos or any other company should always hire experienced managers to take care of these promotion campaigns.
They already worked with Hhampuz and hired him as a signature campaign manager but they decided to stop/ hold the campaign, for perhaps analysis of one first week of campaign operation.
Hhampuz is a trusted and very experienced manager but I don't know the event is launched by the OK.Fun team with or without discussion with Hhampuz.
