Number of edits is a pretty useless indicator.  We have people who've made tons of edits to their user page but never contributed meaningfully to the project.  And, really, we don't usually have a reason to bother wanting to "judge" other editors, so I wouldn't worry about that very much.  Keep in mind that Wikipedia is a "community" only insofar as is necessary to work on the encyclopedia.  Since you've been blocked a few times lately, I can only assume people think you've been disruptive to the project.  From what you say, this isn't at all intentional, so mentorship sounds like a great idea to me.  If you mean well, but have trouble knowing what is or isn't helpful to the project, this is EXACTLY what mentorship is meant to help with.
