Things I've learned at en.wikipedia
 When I made a change and I want that the edition appears, I am a user disruptive because I don't respect the previous edition. When I defend the previous edition, the concept "previous edition" means nothing. Or the dates are ignored and I'm the disruptive again. The two solutions are good.

 Although it is not written anywhere, exist a rule that says that any offense expires in a few days. If you can not give notice of the offense (because you were blocked, ill or without computer for a mechanical failure...), bad luck for you. Here solutions, not justice. And that Pope Time erases the sins is a good solution.

 Open spaces for dialogue and discussion and pledge to respect the result is not a sign of wanting to do things right.

 Apparently appreciate the intention of a user is not feasible, but ignore two serious violations of the rules is perfectly acceptable.

 Administrators tend to be more ruthless with solitary users than with organized groups.

 If a user with a clean record discuss with another user with a non-clean record the administrator only monitor and punish the user with "dirty" record. The other user will not have problems.

Enjoy your toy, friendly and honest gentlemen.
