Instagram is finally clamping down on fake accounts that aren’t controlled by real users.

Instagress, a service that helped Instagram users gain additional followers for a fee, has been forced to shutdown as a result of the crackdown.

Our Twitter timelines have become swamped with ads and sponsored tweets, but if you’re famous enough, you don’t have to see them.

To provide its “VIP” users with a greater experience, and to prevent them from wandering to rival services, Twitter has all but stopped injecting ads into their timelines.

Twitter has today introduced the ability for users to receive direct messages from people they choose not to follow. Until now, users had to be following each other to communicate privately, but the new option lets you receive DMs from anyone who follows you.

Use Instagram much? If you do, you’ll know that the best part about it is the community of users that’s over there. It’s as vibrant and rocking a community as Twitter or Facebook, all wrapped around photos you take, filter, and share. It’s what Flickr wishes it had become. Poor Flickr.

Anyway, you can have followers on Instagram, just like Twitter. And, also just like Twitter, people can unfollow you when you post something obnoxious, post too much, or just post something they don’t agree with. It’s all very democratic.

If you’ve ever wondered who was following you or who was un-following you, Followers+ might be the app for you.

Twitter has rapidly become a great way to stay informed, keep in touch with friends, and generally faff about on the internet. Sometimes, however, that very same sense of humor that has brought you hundreds of Twitter followers can be the cause of folks un-following you. Whether they don’t get the joke or you actually said somethign offensive isn’t hte point here. Tracking who leaves your Twitter-sphere is.

Enter Sayonara, a new app by Nacho Soto that will alert you every time your Twitter stream loses a follower.
