Yes, I used to play Triple Triad Advance, if you had more than 3 alts, you'd get banned, 3rd alt is actually clan account, so you were allowed 2 at most. If you logged in with both at the same time, you'd get banned. Even if you weren't using them to boost the other account.
Also... boosting other accounts by losing on purpose was also gonna get you banned if you've done it multiple times, so...
I didn't play as many browser MMOs tho... so I don't know.
I play Tera (played Rift before), there you can't actually effectively use 2 accounts by yourself so it doesn't matter really. This post was last edited by 101***@facebook at 2016-9-1 06:11
