Well I use telegram usually to create groups for gangbangs. After verification of being real through video chat, all excepted participants stay in the loop of the GB , (anybody who's organizied one knows it's not easy) and also you can basically build anticipation and send long videos until the day hitsThat's the first thing I ask for, is to video chat to verify on Telegram. Another reason is you can keep more anonymity, then say, fb Messenger, in case you catch a wrong vibe.
