If you're gonna block them, BLOCK 'EM!

I agree , I still get numerous comments from the troll I blocked a year ago

if you blocked them you shoudnt get notifications or see the comments

You still see them as "Blocked comment"

unless there are lots of comments you can just ingnore them

Most of the time, I personally ignore them. But why should those who want to fight for fighting's sake be given fuel to hurt you. When WE are merely going about our business! Thank you for your comments and support.

If I block users on other meme sites they don't see my posts and I don't see theirs and I don't get notifications if they comment

They are still trolling, stalking, getting into your life. They try to join forces with other sad/ill memers. What kind of blocking is that? Thanks as always for your kind comments and support, O Giant One.

They should never be able to see your profile, your work (memes) again.

so like Twitter?

If you never saw the stalking trolls again it would be too soon. Sadly, they can't help themselves. Most are jealous psychos who can't stand our camaraderie and merely being happy.
