There is no way for an end user to get removed from either of those blacklists. You can find more details here about levels 2 and 3:


You'll want to contact your hosting provider to let them know about that listing and they can contact UCEProtect on your behalf.

There isn't a way to avoid those blacklists, or many blacklists, in fact. A lot of the larger lists block entire ranges of IP addresses, so you could be blocked even though you did nothing wrong. That's how the UCEProtect 2 level 2 and 3 lists often work.
