Well, I think there is definitely a way they can get back to their patronizers if Para adventure, their telegram account got deleted - which rarely happens though.
And that way is that for them to save the contact information of all their customers so that if for what ever reason, their account got deleted and the number used to sign up got banned for life, they can use another number to sign up/join telegram back, and use the backup contant of their patronizers stored on their device to reach to their customers again.
So what if those guys are scammers with the aim to only collect people's money and disappear, how will their patronizers get back their money after they have deleted their account? What kind of busy person that will even trust this kind of service that is not registered and doesn't have office any where apart from telegram. Are you even on the opinion that that stuff is real?
