ECCIE (and probably P411 if you use it) are still the best sources of info for mongers as they can get it from other guys, and not from ads, or "reviews" from sites that aren't moderated. It's a pain sometimes, but the info is important.
Other than that...Welcome to the internet... in a day and age where a cute girl can just create an OnlyFans and hustle people out of money, you have to be scam sensitive. Even girls you've seen before, living out of hotel rooms, will eventually pull the "can't pay for my room" hustle... sometimes its true - when you sleep 14 hours a day *ahem* and spend all you just got, sometimes you "ooops" awaken to getting your door knocked on and housekeeping kicking you out... but you know.
Do not feed the scammers.
I've literally spoken to girls who talk about sitting in a room joking with their friends about how many people they have to text with a sob story before someone sends them money. The average is it takes about 10 hustle texts before you hit a pay. It's like a slot machine...and guess who's the ATM.
Again, from the big money/deposit scammers, to the can't pay room/flat tire/can't feed kids-self/need gas money/*add in rinsing request here* hustlers, they abound. STG has cleaned up many of the scammers (and notice the HUGE post falloff in the "gallery" view of posts in general) but listcrawler and the like are still mostly scammers.
I'd estimate there are about 20-25 escorts actually legit in the area at any one time (posting and active, not all). There's so much competition that the hustlers just move to the next mark, and even the experienced girls know they will keep picking up clients NO MATTER WHAT. So they pull bullshit. Even girls with ECCIE accounts have hustled clients.
Trust, but verify... or VERIFY then trust
Good luck out there! Enjoy BoomDay
