Green flags:
Official Web site with the most details, if there are testimonies on the web site, the better
Positive Active Twitter account (without pretentions, without arrogance, down to earth attitude, naughty pictures, confident ladies are a turn on, but not to the point of overconfidence)
Reviews (75 % of good reviews, could be normal if there are bad reviews, we can't please everyone, the probabilities are we will end up satisfied if the majority of the reviews are positive)
Tryst account (they go through their own screenings)
Board advertiser is an asset, but not a must, board advertisers are not necessarily a sure bet
Board participation and contribution
Major Red Flags:
Web site with barely any details, only pictures and rates, and nothing else
Fake pictures (doing google image searches, and it turns out it comes from many sources)
Reviews (75% of bad reviews, if the majority is really bad, then it is red flag)
A raving and generic two liner review from a poster that have no review history or just joined the board… (courtesy of Staedtler, thank you)
Negative Active twitter account (Diva attitude, client-bashing to the point of misandry, major red flag, big turn off)
Leolist or annonce123 ads only and nothing else, no twitter account and no web site, it is a gamble, there are hidden gems out there but it is like looking for a needle in a haystack
During booking or texting during inquiries, major use (over use) of babe or honey at every texting sentences
pressuring to book the soonest
say yes to every inquiries just to ensure a booking, and doesn't deliver the goods...
requesting a deposit before answering inquiries (cash register attitude) when there are no reviews or no buzz about her
Too good to be true ads
Constant rebranding ( rebranding can be a good thing, getting a catchier name, however there are ladies who keep rebranding themselves every 3 months or every 6 months, there are some ladies who rebranded themselves 5-7 times in the span of 3 years)
