There isn't going to be any solution to anything that would leave everyone 100% happy but I don't really care about the hurt pockets of sig spammers complaining they've got less places to easily spam in.
Any changes, regardless of what they affect, usually leave some people unhappy. We should not be concerned by this.
Not always easy to judge and enforce consistently. Lauda might have a different opinion on what thread is trash to me etc and if he is removing threads only started by newbies it can lead to inconsistency and people complaining.
Indeed. Unless enforced on a "global" level by senior staff members (global moderators and admins), it is surely going to be inconsistent to a certain agree. However, it is impossible to make it 100% consistent (a certain degree of inconsistency should be acceptable). However, keep in mind that it should be acceptable for section moderators to enforce it within their sub-board (similar to what gruez did with off-topic).
I don't think threads like what would you do with 1-2-5-10-100 bitcoins need to be here or at the least should be moved to off topic.
(IMO) Those threads are, per definition, garbage.
It might be annoying to sig spammers and if shitposters leave because of it then good. Mission accomplished.
Correct. Using something in the lines of "I would leave" or "some would leave" is an invalid argument.
This is something I've suggested. I know a big peeve of DannyHamilton is people giving bad advice/help so maybe we could disable sigs in the main Bitcoin Discussion and Technical Help subs.
Bitcoin Discussion has pretty much degraded to being a waste of time (at least for the majority of the thread). Also, a huge amount of spammers attempt to give advise which usually is partially correct or just nonsense. This is also quite annoying.
