Hello, everyone! 

Hopefully at least in the meta it is allowed to discuss the rules, or at least ask the creator's opinion of how to interpret this one.

Rules:

"Do not ask for Mathchan users to become your contributors, collaborators, volunteers, team mates, mentors, and so on whether for free or for compensation"

Is it true that, for example, you can't even leave your email or telegram? In case someone also wants to research or discuss a topic or article with me in more detail, e.g. at zoom?

Example. 
User: Hi mates. Maybe someone is reading
Helemsky Lectures and Exercises on Functional Analysis, would like to discuss some problems and move together from chapter X, having worked out the links to one article there?
