I mean as you said you weren't directing anything towards selling or seeking for sellers. It was immediately set as a spam ban, triggering the spam filter...If these words end up being censored for example "p***" and so on then you'll know it's not to be said at all and will immediately trigger the ban filter. Some are reasonable and some are not, half the times it doesn't make sense to why it kicks it off but yeah that word definitely sets it off. Especially the reason for bypassing the censor filter.
You should be unbanned soon do wait patiently please.
