I agree that leaving a negative rating for deleting your posts is not appropriate. There's nothing about that alone which justifies distrusting that person.
Maybe now I understand what TheUltraElite meant when they said :
I dont understand why you all are getting so trigger happy with tagging people for every case.
I was thinking if there was anything to do.
If you don't like the idea that your posts could get deleted, then don't post in self-moderated threads. You can't be upset when the OP uses the tools available at their discretion.
