"This is “send your advertisement to millions over email for just $100″ for twitter. A few months ago everyone thought twitter was kind of “opt-in” and you couldn’t get any spam unless you follow a spammer. Back then I said it would be just a matter of time till spammers get in the twitter game and send “recommendations” as @replies . That time has come. I would block such an account when I get the first message from it and I would definitely not follow whomever they would “recommend” just like I stop following those that abuse the #followfriday thing. I think twitter should also block this company." - Mihai Secasiu
