Some interesting takes:
“I have only bought wow tokens with my accounts and bot using my own profiles. I have yet to get banned. I doubt theres any tricks to it.”
“When i bought the tokens with all my accounts a few days ago and redeemed them, all of them got banned”
“Buying gametime tokens with botted or bought gold is high risk. and they will not consider any unban requests.”
“I think their bot detection is really !@#$ right now. I just got back into it and to test the waters, I botted 24 hours for 6 days straight before the account was banned. Also in their email it was stated that I was reported by another player. I doubt WoW tokens are what they’re using to catch anyone.”
