I like your positive thinking .

In my opinion, mentioning or inviting people who can understand and provide guidance on a specific topic is not a bad thing. Inviting a new user to a relevant post with the intention of guiding them can be beneficial for them. Similarly, inviting users to a good contest according to their taste is also not a problem. All this works (I see it in a positive way).

However, forcing users to follow a rule for mentioning or inviting is not right.
