Is there a way to blacklist someone here so their threads don't show up constantly in the main page? I've looked around but I didn't find anything unless I missed something, if someone knows how that would be really appreciated.
No.
But feel free to block me first when the feature arrives, daddy
Not really. I once asked the same question and people pointed me to the Boards Enhancement Kit, a browser extension. However it doesn't really work like I expected it to, lacks features and is apparently not actively developed anymore. I tried it for some time and then uninstalled it, maybe you'll find it more useful.
