I still delete auto direct messages, even if people have verified with me, through whatever means. And I never click on the link in an auto DM. There is just way too much hacking and spam now to trust even your best friends’ direct messages. I’ve had two friends get hacked this week.
I wrote this post years ago, but it is still popular. Things have changed a bit, and I think that companies are trying direct message barrages all the time, more and more often. It’s a huge problem for brands and Twitter. Most end-users, though, will accept them as a necessary evil, and we will all be forced to get used to the new normal (like ads on Facebook).

In the future twitter will consist of nothing but automated conversations between spam bots.
Our shopping bots will just go ahead and buy the stuff in the ADMs that match our keywords.
Then it will be shipped directly to us, so we can consume without having to even read anything.

You can stop Tweetadder from accessing your Twitter account, and that should stop the direct messages. It will also stop all the Tweetadder functions. In other words, Tweetadder will no longer work with your Twitter account at all once you revoke access.

Log onto your Twitter account using a browser like Safari or Internet Explorer. User the pulldown menu under your avatar and username in the upper right corner. Go to Settings. Look for Applications. Click on Applications. Now look down the list for Tweetadder and press the revoke access button on the right on that line. In fact, revoke access to any other application that you don’t recognize. Applications slip in now and then and really, they don’t do anything for you. They are a security risk, also. You can always add them again later. I clean out my Applications on a regular basis.

Following those steps should help you stop the auto direct messaging from Tweetadder. Good luck.
