Hey,
sorry that happened to you. You are right, its a rite of passage, happened to us all in one way or another. Well done for changing the passwords and adding 2fa on where you could, it is a good thing to do periodically anyway.
When you say that he had your real name in the chats, was it your actual legal name or just the name from your email, the one you say is not your real name?
For now, I would also change the settings to stop grey users chatting altogether. You can do that on the settings tab , thats next to the users list and PM tab when you are broadcasting. Then you can just occasioanlly glance the usernames and ban anything suspicious looking grey colored...Once he realises he cant do much he will probably give up and leave you alone.
As for telegram, if you want to keep using it, that is... It is not advised nor allowed, keep all interactions within the site and paid for in tokens for your own safety.
But, if you do want to use it, check the settings, hide your phone number and make sure your contacts are not synced and all the other relevant settings are changed to be as private as possible.
For extra safety, I have also cleaned up all my non-cam socials so that the emails are all different, and the profiles are all very private and that my profile pictures wont come up in any reverse engine searches, aka they do not have my face in them.
There are a lot more safety tips here on the forum and lots of very helpful models, but I will leave you with just one top tip that should avoid the biggest scams;
Never do anything, show anything or ship anything before you have the tokens in your balance.
