I have used interpals on and off for 5 years. Becoming savvy at blocking the scammers, money demanders the outright abusive. Generally found the site lacking the qualities it states it has, there are almost no people genuinely seeking long term friendship, it is more like a revolving door of people constantly coming and going.
The worst part is the lack of moderation when needed with abusive, threatening and other wise nasty people, then my own account after 5 years of good correspondence was shut down for "suspicious activity"? Are you kidding, what a totally bad site.
