if you are logging on and never get to the password screen and it just say "please wait" in a endless loop that means your ip / account is temporary restricted. this is a more aggressive punishment compared to wait in line @ 2.5 million.
if you do wait inline it can take around 14 to 20 days on restriction but if you get the "please wait" loop it can be either 24 to 72 hours OR up to about 30 days and getting a ticket wont help since bliz wont lift the suspension.
there is a workaround for this but it requires time effort and resources. what i do is have ip / account / email active on one residential ip then have another set of ip account email active and fully compartmentalized on another residential ip. if team 1 goes down (and it will) i can fallback to team b. with that in mind try and set up a similar system. since ip accounts and email are all linked dont log into an account that is under restriction on another ip as blizzard will see the evasion and restrict that account too. instead run groups of accounts in parallel this is the best evasion tactic.
Thanks for the write up brother. here's a streamable with the issue, you seem to know of it so I respect your opinion on the matter https://streamable.com/bfxg7u
perhaps you covered it. The password he enters is correct, the botter, and it times out oddly as if theres an issue. Glad to know its a lockout.
