There's a lady I would like to see who had reviews on TER. Now those reviews are gone. Is this a red flag? Why would reviews be removed from the site?
Thanks.

She could have been de-listed.

Providers can ask to be temporarily delisted usually for personal reasons (not active, in a relationship & not working, divorce, child custody, support, stalker, LE problems) and can get reactivated when/if the situation changes.

A provider can be delisted/banned if caught faking reviews.  Posting reviews from the provider's computer will get them (& probably the hobbiest too) banned.  A banned provider can not get "un-banned".
