I don't know about Croatia or the UK, but in the United States its against the law (Title 18, section 2423 if anybody wants to check my homework) to travel to a foreign country to engage in sex practices illegal in the United States. It is possible that Evans' legal problems are just starting.
Some of his financial dealings would certainly get the attention of the IRS. Again, I don't know about the UK or Croatia. In my opinion, Lloyd Evans would be well served by engaging a good lawyer, shutting his mouth (the first piece of advice that lawyer will give him), and groveling for his wife, if she'll listen to it.
Even if he's not broken laws, he's clearly violated Patreon rules and should be reported so they can protect people who may be misled into thinking they are donating to something they are not.
They have pretty strict community guidelines and using money raised on the pretence of being for something else and using funds to engage in sexual practices violate their terms.
