Just got an advertising email from AliExpress. These are quite common and are supposed to be based upon your interests. First page: palm router, JP pups, Abalone fret inserts, no problem.
2nd page- what the?! Now, as much as I am still a red blooded male I can assure you that I haven’t been looking at kinky sex gear- and I’d hardly be telling you lot if I had!
It does make you wonder how these algorhythms work!
