Replying to Can someone help me fix facebook?

I don't know if anyone else is having this problem... But almost every time I sign onto Facebook I have at least 25 notifications saying "This person" has made a comment on your photo" Or "This person" has made a comment on your wall." I will click the link to their comment, but it will bring me to an application page... (I am not a member of ANY Facebook application. because they're retarded and I use the website solely to communicate with distant friends...) And I don't want to join the app. to see what they are commenting... I have even confronted the people via Facebook chat asking them "Did you comment on my photo?" To have them respond with "No, my wall is doing that, too!" Does anyone know how to get rid of this shit? It is obnoxious! Thank you!
