I don't think it's an issue regarding her site, the concern was that she suddenly disappeared from a lot of her social apps and her long term phone number stopped. Mint and the web owner are actually close friends but I have not been in close contact with him either - though I doubt they ran away together.
Mint was never really someone who was on the scene or had a past to run away from, she was very smart and never actually worked in a bar, she was unique in that she was actually more fantasy than many of the other ladyboys we all admire here. She knew how to create an image and character, and those who were close friends knew the real Mint is someone very different form her website image. She also co-owned her website, rather than getting paid for what she did, so she earned money without doing anything - very smart girl. I can't image she would do more website work,s she saved well and invested in some businesses close to her home.
She may well have had problems with her long term American boyfriend again, as you say, about a year ago she had problems with him and stopped her phone for a month before and was planning to run away to work in London to get away from him. But it seems around 5 moths ago she disappeared from all her apps and lost contact with some close friends again, which was the concern. My bet is that she did make the move to London and is maybe working there somewhere, or she decided to stay at home and work in her shop, and distance herself form the party scene, opting for the simple life. I think no one her could have a bad word to say about her, she was always well admired.
