Congratulations on your first earning.
But I still don’t see any reason why someone would be angry or hold any negative thoughts about a forum that has nothing to do with why your transaction got stuck, you already mentioned the reason why your transaction got stuck (low transaction fee as you mentioned) and I’m guessing it happened during the time bitcoin network was congested so there’s actually no need to include the part about how you felt about the forum during your waiting period.
So I’d advice you edit that part out because I feel you’ll definitely get bashed for that.
