Alright, first off:
Please remember to sign all of your posts on talk pages.  Typing four tildes after your comment ( ~~~~ ) will insert a signature showing your username and a date/time stamp, which is very helpful. 
Secondly, I understand your point, but userpages are about users, not for commenting. Talk pages were created for this purpose.
Now that the warnings are out of the way: If you have proof, why not post it on the article's talk page? That's what the talk page is for. ) Post something like "I posted [insert what you posted here] because [insert reason here]. I was reverted because it looked like vandalism. The proof it is not vandalism is [insert reason here].". Make sense? I thought it did. —     (Got something to say? Say it.)
