I don'tknow if I've ever asked, but if I ever did, it was because I had really liked the song, tried hard to learn it but really failed to figure out the bassline (and maybe some other chords).
I started off by self-teaching, so my only weapon was paying attention to what I heard & trying hard to figure out patterns.
This is where theory came in to save me. I learnt the basic patterns before I even knew the theory
When I learnt the theory it was confirmation & I just practised more.
I enjoy the posts & learned (& still do) quiet a chunkful from them because I do my own analysis of them & derive other stuff.
To me, playing from what has been posted is like saying: Play that again Sam!
I pick up a thing or 2 & apply it to other songs.
But over time, I've preffered listening to , say, solid blues or other genres of music where I can pick up a new progression & try to apply it in my music vocab in any song it fits into.
ConclusionI do encourage requests, but you should be willing to pay a minimum labor fee to show some appreciation- it takes a long time to write
(It's also very enriching by the way..I re-inforced my learning by helping requesters
)
