Most everyone here knows this but for the 1st timers, here's a schoolboy primer.

Many trannies are in unending mode of running away from poor reviews or comments disclosing them as scam artists or worse, so it's difficult to identify them from month to month, or website to website, or in some extreme cases two different ads posted by a rob in the same website....  you know, like a virus that mutates so fast a new more virulent strain ravages you after the old one that tormented you has been killed by antibiotics or other drugs.

Phone numbers:
somewhat but not always reliable.  TSs change their phones or sometimes share phones with others.

Pictures:
always suspect, many highly photoshopped, intentionally soft-focused, posed to hide unattractive features, 10-15 years out-of-date, or simply stolen off other websites.

Names:
Practically worthless.  Even those who deal fairly with customers change their name and persona to monitor the success of their marketing.

Eros Verified:
a sick joke.

So as Confucius said, freedom requires persistent vigilance ... no wait, that was someone else.  Confucius said "Rots-a-ruck, mate!"
