I was looking at the reviews of a provider that I have been interested  in and noticed that a fairly new review that wasn't good was taken off a little while later. Any ideas on why that is? Made up? Felt bad?Lied?Threatened? Not that I'm paranoid but you never know.

and made a convincing case that the review was bogus, so TER took it down.

It may be the case for some banned hobbyists, but definitely not all, so don't make blanket statements. There are many members who have been banned whose reviews remain.

Mrfisher mentioned two, and I would think those are the two most likely scenarios.
Other possibilities:  
1) The reviewer made a mistake (like maybe reviewed the wrong lady with a similar name?)  
2) The reviewer needed to edit the review and asked TER to put it bsck in edit mode in which case it will eventually pop back up.
3) Too much personal info was given in the review.
4) Another member (neither the provider nor the reviewer in question) reported the review as fake or having some major discrepencies, or somehow violated TER's rules.

going to tell you.  You have been some real good possibilities.

and all his reviews including mine were removed. So my statement is partially  true. Seesh Storm no need to get pushy, gear down big rig.  

You made your post as a blanket statement and it needed to be corrected.
