The difference between refusing private chat and refusing private chat

The differences between the two are as follows:

1. When someone sends a private chat request, they can politely reply to decline the private chat. This also means that I don't want to talk privately. Refusing private chat is usually based on personal or time reasons, or prefer to communicate with people in public.

2. When someone sends a private chat request, it will clearly indicate that they are unwilling to chat privately, and give some reasons or explanations. Refuse to talk privately, because you are not interested in talking privately with each other, or you are skeptical about each other's motives or intentions.
