If I ever did delete or edit any postings it was because I found it objectionable, which the TOS permits. That's why moderators have an "edit" button.
"Without limiting the foregoing, CureZone and its designees shall have the right to remove any Content that violates the TOS or is otherwise objectionable. "
Everyone who posts in VWT, and all other forums, run the risk that what they write it might be deemed objectionable and removed.
