Can i be banned for?

I post here cuz from 2 weeks i can;t get in riot support site anymore, tried everything firewall internet reset etc, none worked, i think they banned me from the site, my ip at least, i was able to enter it with a vpn proxy, did not post from there cuz u know. Can i be banned for saying things like we lost drake cuz u went there , or we lost the game cuz u did not follow us, and when someone flamed i told x champ reported.I tried to reform and i can say i did, in the past i was horrible flamed at everything, bad flame like wishing cancer etc.Now i can say i am pretty clean.And sometimes i say i go afk but say kappa after or jk.What do u think guys? Also i want to know riot why i can;t reach ur support site. Thanks.
