Is this normal?

The server cost is not too high to do blacklist cleanup on login.

Here, I'll derp it down for you.

1) They do not delete banned characters. (they have their own reasons for that, And I'm not going to get in to it.)

2) BL is client side because that is a process totally up to the user. there is no reason for them to keep track of your optional data that
has no bearing on the ability to play the game. this is a cost saving measure, same as action bars, UI, and Macros. These are user settings
and have no effect on gameplay. The cost to manage the remotely is too high and would just bog the servers down.

3) No company can change files on your computer without your consent. When you change your UI, the action of you doing that is your consent.
SE Cannot change files stored on your computer without your consent, and/or posting a log of changes made.

4) Yes, the server cost is too high to be checking the tens to hundred of thousands login's per hour over all servers. it's is not necessary.

No need to be insulting because we have different opinions. You don't think it's worth the server load. Fine. I think it is.

And sorry, but your comment about them not being allowed to change things on your computer without your permission is completely incorrect.
