Do 2 day bans ever go away or expire if so how long typically?

Pretty sure they do, but i think it takes a couple years. I have one that has an expire on it but it was from like 2013 or something crazy like that

They do expire but takes a long time.

thanks

They expire after 1 year.

Only thing I'm unaware of is whether or not if you bot again after it expires, if it still goes to perm or another 2 day. I'd actually like to know that aswell.

To be fairly honest I can't see them allowing back to back botting offences, just depends on their mood I guess, a lot comes into play when they deal out the two day bans, for eg. what you are botting, how many resources you have brought into the game over the amount of time you have botted, how length of time the account has been played for etc. They seem to be more lenient with giving out bans to players that have been around longer.

i believe it takes a year 

I had an old account that got 2 day ban. Mine went after roughly a year didn't check the exact date so

After 1 year i believe they expire
