Just to give you all a heads up, Twitter is getting pretty good at linking accounts together. You should all start using proxies when using automated tools from multiple accounts over a short period of time - this applies to automated follow/unfollow, tweets, etc. They're banning first and asking questions later. It looks to me like they're basically looking at the number of accounts that are accessed/updated from a single IP address over short periods. Even if you access through the API, this appears to still be an issue. The banning appears to be fully automated, as yesterday alone I lost over 1,000 accounts WHILE I was doing an automated batch of follows. Also, it's now official that your account needs to be "aged" for your tweets to show up in search results. Basically, for your first week post just a few, non-spam tweets. It's important to post some tweets, or you won't show up in search results regardless of how old your account is. After a week with a couple of "headed to the store" type tweets, you're all good. This banning has caused me more than a few headaches this week. I'm going to have a mass funeral for all the accounts that died. But it inspired me to get creative and I'm mounting a comeback the likes of which they haven't seen before . The cleanup also provides an opportunity, because it kicked off a metric ton of spammers who won't be able to adapt - less competition .
