I have been marketin on twitter for a few weeks now. I can send thousands of messages on accounts with no problem ifi dont send a link. I notice other marketers sending thousands of the same message and link on the same account. There accounts die but they sen like 3k tweets on the same account with the same msg and same link in the tweets. If I try this i only get like 5 to 20 tweets out before the accounts die. Is this because they are using aged accounts? If so does anyone know how old the accounts have to be in order to send like this?
