Hey if someone blocks you on one instance but you or they have alts where you aren't blocked, don't fucking talk to them. That's crossing a huge boundary and incredibly fucked up.
Imagine if two people were talking through a door on of them closed it, then the other person went to a window to keep talking to them. Pretty fuckin' gross, huh? Block evasion is the digital version of that. Regardless of platform, it's not okay.
