Easy way: Donate.

Harder way: Do productive activities on the site that gets the attention of a mod/admin.

If you're talking about the one warning given to you by me, improve the quality of your uploads to the point I'm confident you get the point/idea and can consistently do it on your own. I may then be inclined to delete that negative record. Just keep in mind unless you yourself are confidant in that task (and have a clue), you invite many other opportunities to gather more negative records.

I'm not trying to dissuade you. I'm just giving your the facts of the matter. Your last major deletion was 2 weeks ago (by me no less...), so you got your work cut out for yourself if you want to "earn" a positive record or have the Warning (which is a month old or so) removed.
