Goodwill protection claims. How to avoid?

Question

Law in IT

We want to open a resource on which to write notes about various pseudoscientific charlatans and impostors, including various coaches and success coaches (I hope everyone read the article on the "personal growth training" lurk).
However, a legal issue arises. Many of these people have businesses. And if I write that Petrov is a liar and a charlatan, because... theoretically, they can try to hold me accountable for [crossed out] disclosure of trade secrets [/ crossed out] infringement of business reputation. Question. How to avoid it?
Suppose I open a site on this topic.
1. It's where other people rip the veil off success coaches. Everyone sits under nicknames. Who will be responsible for the publication? Me or the person (in this case, just a nickname) who made this post? Who will be sued against the owner of the site or against the nickname?
2. What happens if you register everything for a citizen of the other side? Do I understand correctly that in this case, the procedure for filing a claim will become hellishly complicated?
What other options are there please?

Answer 1

Use legal methods without a direct attack on business reputation,
adopt their own weapons.
For example, they often create a rather negative image of a working person as opposed to "successful people". You can, in contrast, spin your phrases, "loafers-coaches", "air sellers", etc.
Regarding the facts of fraud, as written above, do not write Petrov = fraudster. "Some of Petrov's clients are ready to conduct an examination regarding the recognition of the entrepreneur's activities as fraudulent in accordance with Article X of the Criminal Code of the Russian Federation" - in a phrase of this type it is much more difficult to show the fact of infringement of reputation.
Write about lawsuits, cases, let people from the court provide materials. If a lawsuit is actually filed, this is not slander, but a real fact.
Further, you can use humor and other methods of information warfare.
Citizens of strange states - also excellent

"Watch the Bazaar!"
Seriously, these types of lawsuits are relatively hard to spin. Provided that you will not be unfounded!
