I applied for free web hosting some 2 weeks back but it was rejected because I had received a warning on the very first day of joining. I figured I'd reapply sometime later when my credits would have increased and the warning would have disappeared. However the warning level is still at 10% after more than two weeks (now I'm thinking I should have made a new account as I got the warning on the very first day when I hadn't even read the rules). What I want to ask is : Can I reapply with this warning level or if there is something I can do (like a tutorial or something, I know a quite a lot about programming) to get it lowered? If not then how much longer do I have to wait for this to pass?

You will usually get refused hosting if you have a warning. Usually, moderators remove the warnings after around a month, as long as you have behaved yourself Writing good quality posts, not copying material, and generally obeying the rules will all help to get your warning removed.

When you get hosting your credits reset to 3, so any credits you accumulated will be gone.
Just continue with your giid behavior, and befire you no it the warning will be gone

I had a warning level after I let my friend bryan talk me into cheating the hosting system,

After a while it got lowered. I think the thing that actually got me noticed is I replied in this very forum. I helped a member with something. I don't really remember what. Anyway, just wait. It's not a good idea to make multiple accounts because you might get warned for that. just be active a while, and try to get noticed by admins who can lower your warning. Post in here and try to help other members.

Yes, re-apply now since your warning level was reduced a couple of weeks ago...

Or you could do what i did, and that is buddy up with jlhaslip and
he can help you reduce your levels, and make better posts.
