Thanks for reporting, nice to see we are at the right board, so let this discussion keep going.
Based on the link he posted, maybe the one he accused posted there but deleted it.
When I look at the post history of this chenli1995, it looks like he has not only one telegram account but many.
@Botnake is right, even if this newbie account is tagged, he will not be able to get back the money got from him by the scammer. Because it can also create a new account again.
All you can do OP is forget that and move on. Just think of that as a lesson for you and I hope it will not happen again. Do not just trust especially newbies and do not have good ratings ...
I think he should PM chenli1995, and tell him about this thread and if he doesn't respond, that could mean he is guilty but when there is no evidence, it's not right to red tag an account IMO. To OP, he just need to learn a lesson from his experience.
