Since no one here seems to know what the heck is going on... Listen.... Things are made to fail. That PS3 controller is no exception.
It has a foam strip (yes, foam) holding it's contacts in place. When the foam flattens, the contacts loosen up, and rub things they shouldn't (giving you unwanted button pressing).

Now, we're talking about foam here. The piece in the controller specifically isn't even worth a penny. So, don't go out and buy a new one. Open the thing up. Watch a video on youtube.

I open my controllers up on the first day I get them, because I know it's something that's going to happen eventually. Anyway, wrap that piece of foam in 2-3 layers of electrical tape, or something. Not too much tape, or it wont fit back in place.

But, I wouldn't buy anther controller because a part less than a penny went bad. It's foam. Foam gets flat over time. So, "playing like an animal," wasn't the case....

I've opened up several different types of PS3 controllers over the years.. No matter what they change, that foam is always inside. You may need to find the video that matches the model of your controller, and watch it TWICE before your first opening if it's your first time ever doing it. You wanna have an idea of what you're doing so don't try to follow along.

But, he doesn't know wtf he's talking about.................  Keep in mind, this will happen to every PS3 controller, because they all have the foam peice.  Give it time.

sixaxis have a weaker build quality and DS3 have much better analog sticks. IMO

i think the sixaxis is no more... only if you buy them used on ebay.

don't think the vibration is the cause of this, but if you want you can turn the vibration off.

thanks, you know what i should search on youtube? like what to type? and do you have a link to a video?

Same price as the DS3 on Amazon :D

I suppose any video that fixes the problem of the controller "pressing buttons on it's own."  No specific thing in particular.  But.. Hold on, I'll take a look-see...  Just type "PS3 pressing random buttons."

There's a ton of videos that came up for me.  As I've said, it's a problem that will happen to every PS3 controller eventually.  Just look and see how to open it.  Watch it a few times before your first try.  Be very careful with those motors, or you can kiss vibration goodbye unless you know how to solder them back together.

What I do is fold the motors back onto the circuit board and be careful not to let the motors move until I'm ready to put them back in place.  Have a magnet, or something handy for screws...  Putting the back plate on is going to be trouble, so be patient.  Don't break your stuff.

When you're ready to put the back plate back on, start from the top (between 1&2 shoulder buttons).

Yep... He did everything i would have done.

i think that is stale stock... i think sony did stop making them.

great for folks that want one.
still DS3 is a better controller IMO.

That's like turning off sugar in your coffee.

LOL... i know... i have mine for 3 years now with vibration on all the time and its fine... very sugary...
but someone said that vibration could cause a malfunction in the controller... i don't believe that but if he was concerned about vibration, the option is there to turn it off.
