Claim page won't stop sending confirmation emails

i signed up for emails on this page: Nyan Balloon

and i have received 20 requests to verify my email and IT WILL NOT LET ME UNSUBSCRIBE.

PLEASE FIX IT

Hey! We introduced a bug for a few mins that caused this. It should now be resolved, are you still getting new emails?

Sorry for this!

LOL, thats funny, though its good to test for that, yes, it stopped. Thank you!
