You can always "watermark" your audio, or only post a section of a song you are struggling with, or clips of each section. That may make it a bit harder to bash, but not in all cases, especially if you are asking a specific question or for specific advice on a certain issue. By watermarking, I mean overlay some kind of sound or 1-second beeps over the music track at certain intervals, or you can just clip a slice of audio out so there's these little gaps of silence. That would be better for the EQ checking I think. That way nobody can steal your whole file and just use it.
As to the intellectual property aspect, it's possible someone could steal your ideas, but I can't say I have seen/heard of any case of that in 7 years on both this and the previous forum (RR). Is the fear or impediment of that really worth not moving forward in getting your stuff done or out there? (talking about the "psychological payoff" thing)
You can always ask for the specific advice you are looking for. I have frequently advocated for that, as just posting something and leaving it wide open can bring a bit of chaos to the thread (being all over the place), including your own frustration and also perhaps wasting the time of people commenting on things you probably won't consider anyway. Of course people may comment on those things regardless, but if you have specified your challenge you have at least attempted to take the thread in the direction of solving your problem with the least amount of effort.
