* Do I run the risk of being blacklisted for this practice?
Risk? Blacklisted where?
The risk of another ISP filtering your traffic for this is very low, almost certainly to the right of the decimal, but not mathematically zero to infinite decimal places. As I mentioned before, the risk of geo-loc providers ignoring any of your manual updates in the future is higher, but still low. Most of those things are automated.
I doubt the geo-loc provider will blacklist you unless you give them detail locations (e.g. an exact building) which have no relationship to you or the users at all. They get embarrassed when police rely on them and then knock on the wrong door. There is some risk of content owners blacklisting your entire address space on the grounds that you have been caught circumventing their restrictions. I have no idea how significant or insignificant this risk is. If it happens, good luck getting it undone. There is some risk of legal action should a government entity rely on your information to mean that data in its unencrypted form has stayed within a particular locality when it has not. For example, China expects that its citizens browse the web from behind the great firewall where they can control and interdict information they don't like. I have no idea how significant or insignificant this risk is. Understand that while you may not actually be in the other country, many countries have treaties which allow cases to be brought in the resident's country when the behavior is unlawful in both countries and at least part of the actual activity happened in the other country. Fraud abetting some other unlawful behavior is broadly unlawful itself. Regards, Bill Herrin -- William Herrin bill@herrin.us https://bill.herrin.us/
