Spam through habrakpochta and undersubscribe letters

Recently, a letter was sent to habrapochta asking for support of some objections (or no objections - I didn’t get it, not interesting) about the prizes at Habré. I filled up the letter, sent another one with the same call to forward. Both letters were sent en masse, the recipients had solid lists of users. The second also flunked. But then those who received it began to respond to the first letter. Notifications of every reply come to my personal mail. When I click on the "reply" link (or leading to the letter itself in the hacker), I get to 404, since the letters have been deleted. Do something, please. I do not have the desire to receive spam from Habr either.
