If I understood the premise correctly (you don't have to post in either of the threads to participate in the LTC part of the giveaway / low-effort bounty) then yes, that's completely fine.
That's good to know.
I understand the point you made at the start of this post, but considering how difficult it is to interpret the rules of Bitcointalk by regular users sometimes, and the fact that OP had clear intentions to give out bitcoin by escrowing the coins, could he be pardoned and have the permanent ban changed to a 2-week temp ban instead? His original thread would have to be re-written to be in line with the rules, either the way I explained in my previous post, or any other way that is better and/or more suitable.
Each ban is reviewed case-by-case and the decisions the staff make in this particular case don't need to have repercussions on other similar cases just like unbanning a user who copy/pasted wont make all copy/pasters unbanned.
For the record, I have not participated in the campaign by OP nor do I know him. Just in case someone asks. But I don't think that with him gone this community will either be safer, cleaner or a better place.
