I am very, very disappointed to learn it has finally come to this, but with all the issues accumulated in the last few years, I suppose it was inevitable. Sadly enough. I'm not thrilled about Bikerdude's banning, but he had plenty of warnings and good-natured heart-to-hearts with the rest of the community about some of his habits as a seasoned TDM contributor. In light of all those warnings and the drama it was causing in this modding community, I can't say BD's banning is unjust. He knew very well he was playing with fire, for a fairly long time now. He was warned plenty of times, but I suppose his compulsion to edit others' FMs is just too strong (or something).
I know bans happen only very rarely on these forums, but I'm of the same opinion as the one I hold on another forum I frequent (where plenty of people have gotten banned for repeated bad behaviour or questionable behaviour): Sometimes, the only solution to stop a person from repeating their questionable behaviour is to stop their activity in the community for good. I am exceptionally disappointed this ban had to be carried out, but as Springheel and others have said, Bikerdude had his chances. He's a grown adult. He could have course-corrected at any time.
Everything useful he did for TDM in his many years on the development team or as an individual mapper is laudable. With me documenting various stuff for TDM over the last year, I did notice he contributed a great deal of highly useful stuff. However, as Bienie pointed out on the first page, if Bikerdude has a constant compulsion to edit other people's maps, then his banning will probably be helpful not only to restore a sense of calm and trust to this community, but also let him rethink things. TDM might be his hobby, but when a hobby starts becoming intrusive in the work of other contributors to that hobby, something is not right. It's a good point to step back at that moment, relax, etc. Hobbies should never consume us.
At this point, Bikerdude had only himself to blame for not listening to previous pleas and advice. I'm pretty sure we all want to get along well here, in a civil and friendly atmosphere, helping each other and respecting each other (and our works). I don't think Bikderdude wanted anything else, but he became blind or deaf to the warnings of others that he's began to cross some acceptable boundaries. Being too nosy and immersed in others' work becomes rude after a point, not merely just an interest in helping. If something is a cooperative work, some consent of others is required.
I'm sad this had happened, but for a while now, it really felt like this was going to happen sooner or later. I hope Bikerdude won't miss it here too much, and I wish him good luck with whatever positive endeavours he engages in and works on.
