Like Rambo said, over sexualized, lots of emotes, always online, answer messages daily, saying something is exclusive, fake limits for the discount trial like "only [4] spots left".
Once you see enough of them you will get it, and the girls that use this tactics and are not with an agency are usually scammers anyway.
"NEW Extra EXPLICIT CONTENT!!!
AND LIMITED TIME FREE VIDEO IF YOU JOIN RIGHT NOW!!!😈
Only [2] Remaining 😏"
the 2 examples below i know for a fact that are run by an agency:
"My New Year's resolution is to be your gf🎉😘 For the next [4] subs⚠️
Come find out how naughty I am 😈"
"55% FLASH SALE 🍑 FOR THE NEXT 50 SUBS 💖 TODAY ONLY‼️ COME WATCH MY NEW EXCLUSIVE G/G COLLAB 👯♀️🔞 INCLUDING TOYS, BONDAGE, AND MORE 🙈XXX"
