I'm sorry to see you go, though I don't quite sympathize with the reasons you have listed in the post.
I can't remember the slightest thing that could be wrong there, no rude language, nothing wrong at all.
What was wrong was that it was a public discussion about another user, one who wasn't even around. It was deleted due to that. Not to remove any discussion -- there are plenty of posts mentioning the suspension that are still around (some of them yours).
This seems to me more and more everyday, a personal crusade of a specific moderator against a specific user. And now the traces are being covered.
The user wasn't even suspended by the same mod each time. As mentioned before, it's about the site rules, not any personal vendetta. And I think there has been enough discussion about the rules, though if you want them changed then you'd have to bring them up on the main meta (where I think it's been brought up before, not sure).
I don't think this was done to cover the traces of anything. Not in the sense you mean, at any rate. We had a good member who is no longer here. Is there any point leaving a post around that discusses his suspension? One that contains various dissections of his character? And things that border on personal attacks to him? Is that really something we should preserve?
We don't think that the suspension was wrongly carried out1, and the mods will never claim that the user in question was never suspended (and we know that the community will remember). With this in mind, there isn't any reason for us to do this to cover our tracks.
I am not one of the great users here. I don't pretend to be one of them, and of course I don't expect my decision to have any impact. It is only that I cannot accept this any more. I leave the site. Thanks to those who answered my questions and discussed some ideas with me. I hope that my few humble answers were useful to somebody.
Again, sorry to see you go. Thank you for your contributions.
