I did not receive the payout I posted over the required 20 posts because posts related to gambling are prohibited, but on their rules, there is no specific rule that says so
Lol, I think the CM should also state in the OP that disqualification without payment can also be based on new rules in the future that have not been announced even 1 minute before the week's round ends. Or specific rules apply to certain participants and unfortunately you will find out after the week ends.
Seriously, I think this rule doesn't have to apply for the first week and is worth paying for (with constructivity requirements). Likewise the following week as long as the rules are not written publicly in the OP.
