a ban only happens when an account is closed. a temp ip restriction is temporary.
there are different types of ip restrictions
a checking version means you made too many games, you can log into your account but will have from 1 million to 3 million wait in line timer. sometimes the timer is 500k or 50k. this can also happen by spamming invalid skills on a character or attempting to drop the character from the game with invalid packets and you will ghost out of game - still works LOL.
a hard ip restriction from a vpn will show up as you click to load the account and you will just see an error box that does not move, you cant log into your account
verbal abuse of players, threats, cdkey muting causes a account login restriction
botting - this is a bit of crap shoot here in if you spam messages in game it can simulate a 14 day ip restriction as if you used a vpn, what also causes realm down is leaving a game too fast with too many characters at a time on the same ip.
accounts cdkeys emails ip are linked. this show up in he can get on another ip, load an account but cant make more then one game before realm down because the cdkeys are blacklisted until the time expires. get another set of cdkeys, ip, backup account and register with another email and dont mix them. allow for the time to expire and set better configs.
