Attract customers

Hi everyone, i have created a website on wow where i sell things like boost 90-100, conquest points ect ...
My website is nearly finished now (i can add new product, some guides, ...). .
My main account has 2.5M golds, spectral tigger, the insane pré-nerf, 10 lvl 100, about 600 days /played so i don't want to get banned.
I want to put annonce in /2 to attract players to my website, have you got some tips for that ?
If i take a new account, will they ban my main account because of same IP ?
A bot can put annonce in /2 all the day ?

Thanks for your tips ! :D
