bots and phising attacks are just trying to get someone to actually click. It is brute force attack. So the method is to post as much garbage as all possible that out of all of those junk posts someone clicks a post just once so they can get their account details and use it to do it all over again. There is no way to stop it unless we had the admin of the board in place who can change the permissions on the board which would then block user creation by these garbage posters. As always I have a different board which the scammers will not follow already in place. All you have to do is create an account over there.
