Each of us has the right to request that any odd FReeper not post to them if they feel there is nothing to gain from interacting with said person.I hope that's not a rule. I don't think it's a good one.
If a person makes a comment on this open forum, then that person should expect a response from anybody.
The only requirement should be that the response doesn't brake the rules.
I'm sure that there are many rules that posters might not agree with, which is why I am glad that one guy makes all the rules, and the rest of us can either adhere or count the seconds.
