I don't remember Nathrixx added source link or not but ETFBitcoin pointed out the source that OP used without quote (not sure about source link, as said).
Are you sure? I don't remember doing it and i can't find any relevant post using this keyword.
news about being banned for an account is quite rare in my ears..
Surely you have encountered newbie with 1 post who make off-topic reply which include random link. That kind of user who share shady website/perform SEO spam is banned on daily basis and i report them almost everyday.
