New type of spam — Google Form invite spam

A couple weeks ago I started getting really weird emails in Russian. They are invites to fill out a Google Form, but they are just spam links.

Update — No solution yet, but tons of comments and upvotes on this Google Support Community post.

Now I am getting multiple of these spam emails a day.

I assume since they are Google Forms, they are slipping through the spam filters.

I asked this question on the Google Docs Help Community. No answers yet.

Anyone know how to block these?
