This is well written and while I'm not trying to excuse what a lot of these noobs do, I think it's understandable to an extent.
It's hard - really hard - being a newbie on here. You spend a considerable amount of time writing a post which ends not not getting read or commented on.
That being said, I believe you are right and these practices will only irritate people instead of getting them to follow or upvote you, so they should be stopped.
Good that you understood the issues I raised here.
