How to get facebook to stop putting those trick advertisements on other peoples' walls?

[Matt A]

On facebook I have noticed recently that those stupid trick advertisements are being posted on everyone's statuses, under the name of a user. I always had thought to myself that those users had probably clicked on an advertisement or downloaded something stupid to get it.

Yet now I see myself having the same issue.

I had been on facebook yesterday with no problems. Yet I wake up this morning to find out that I made over 100 comments on other peoples' walls, all saying things like:

wat's up this place forgot to put any billing page. I just got an iipadd, didn't have to pay. get yours! hurry be4 it is fixed.
http://apps.facebook.com/g​razeize/?mvfiuexp
http://martpadsnow.shop.co/?mv​fiuexp
apps.facebook.com

or

wat's up this place forgot to put their checkout page. I just got an ipaaad, didn't have to pay. get yours! hurry be4 it is fixed. http://apps.facebook.com/g​razeize/?hqdlsqxp
http://martpadsnow.shop.co/?hq​dlsqxp
apps.facebook.com

and many other things of the like.

I'm going to end up spending the next half hour or so deleting all these stupid comments.

In the past few weeks, I have NOT downloaded any apps on facebook or clicked on advertisements, nor does my computer have a virus (that I know of). That includes not clicking on the trick advertisements I've seen/been posting.

Why is this happening? How can I fix it?

Please help. I'm desperate!

(BTW, I highly suggest that you DO NOT click on those advertisements that I've shown as an example!)
OK, I've done as you said. Now I'll see if I keep sending them. Before I did this they were still being send out continuously for the past couple hours. Hopefully this will work.
Nope, didn't work. They're still being sent out. :/
