tmwilliamlin168 is on read only mode right now. He wanted to message Mike as he feels that the decision to mute him was accidental. Here is what he wanted to convey:

Hi, I received a system message about a read-only mode and I suspect that it has to do with my comment "Fact: If you do competitive programming then you will die" (or something similar)

I think the moderators misunderstood my comment and took it as hate / threat. It was supposed to be a joke, since everyone dies when they get old, and the condition "if you do competitive programming" is unnecessary.

I hope the moderators of Codeforces can understand that I did not intend to be rude in any way.
