Yes, it was unfortunate. The funds may have never truly been at risk but it was still extortion as you used them as leverage to get the the posts removed.
I had agreed to return the funds to @theymos before I had even realised that the posts had got deleted (I only noticed that after I read @theymos reply to my apology).
Even @theymos has stated that their removal had nothing to do with my "stunt" and was just part of normal moderation.
Obviously yes, the posts should have been deleted, and that user had already been dealt with before you posted that thread (though those particular posts hadn't been deleted yet). Only reason I held off deleting them after you posted the thread was to give you a chance to rethink your actions, which is also why I responded to your thread so quickly pointing out what you were doing. It was extortion, whether that was your intention or not. It was also very insulting that you think we would value 50 BTC over our integrity (assuming we disagreed about moderation of the posts).
It wasn't about the posts, it wasn't about the funds either. It was about you, and the way you conducted yourself wrt your contractual obligations.
Also if it would be of any help then I will gladly "refrain from posting again" in any topic other than that of the CIYAM project topic (the work is more important to me than me being able to post elsewhere on this forum).
I'm not sure why you think segregating yourself from the community would help.
I may change it to a neutral someday, I don't think a single mistake should haunt you for the rest of your time here, but that day isn't today.
