I've had success in the past but Yahoo does shut down accounts they think are spammers - they got me in the end. LOL! I had an account i used to join thousands upon thousands of groups and when i lost that i just couldnt be bothered to rejoin them all, which i did by hand as i couldn't find an automated way of doing it. If i was to do it again, i think i'd spread my joining of groups over multiple identitys.
