I personally won't reveal the username since it easily reveals her digital footprint. Personally, I don't think it would be a good idea to reveal it, since Leaflit finally listened and corrected the main flaw of her de facto Discord server. I think it would be very insensitive to reveal their personal information after they did that.
I already dug through to see if there were any potential connections. As said before, the only connection is the username. I even found a personal email address, and I had someone check to see what websites it was connected to. PornHub was not listed in the results, and other websites were that had her username on them. Also, when I was digging through, I found another porn site (Fansly) that had an account with the same username. This account was completely empty, and it also didn't show up in the results for the email lookup.
I don't believe the PH account is hers, since it would have shown up in the list. It would be very strange if it was her, since it would mean she used a different email but used her same username. They have plausible deniability, and all the information known so far supports the idea of it likely being a coincidence.
