I am asking for answer from bitcointalk community how to handle people who spam topics,
and haters who try to destroy some project with attacks, spam and creating multiple accounts with spam purpose with no proof?
Thank you.
Trolling is easy to deal with. You demonstrate clearly that they are lying or incorrect. If they continue to present their statements as true or correct they will be warned or banned. If it is clearly false they are deliberately trying to mislead members which is dangerous.
If they are just continuously making negative claims about you that they can't substantiate then that is something you could call for public review. They need to substantiate to continually throw negative claims at you. They need to provide compelling or have some strong and reasonable grounds. Like if every thread they were claiming you were a scammer they should be able to provide evidence of that when called on it.
You can not expect protection outside of that since that would require bias. The truth should protect you but here that is not always enough
