Sure, I created a completely new account for testing porposes. So I just tested it with one account, to see if I would get a ban, and if I would have added eWhores or not.
Yes, I think you could apply this with 100 accounts, too. You could scrape the e-mail-adresses from the specified-search-results on Twitter and then create a list full with those email adresses. If you have a list created then you can use your favourite facebook-friend-adder software/script to get those emails addet to your accounts, just as you would do it with a random email list.
