What do you do with spammers who want you to support their PH launch?

I get tons of "invitations" in my social channels and e-mail to vote for PH launches. Even if I respectfully deny, because I consider this a spam I still get messages like "it's just one click". I am sure lots of projects strive for that click and think that putting artificial clicks will change their business. It wont. Fake is a fake. I do support projects that I see posted and have a chance to try them. They of course need to contribute something to the areas that I am interested in.
