Okay, I've noticed something going on lately. People make stamps that are huge. These stamps are then posted on profile pages which make the profile pages stretch. Is there something that can be done about this?
I would agree that I've seen a growing problem with this as well. All I can suggest is that the stamps be scaled down to a smaller size.
That explains why I can't get my profile things looking right! Thank you for posting this! I was tearing my hair out trying to figure out what I was doing wrong.
You can block the offending member until their stamp is off of your profile.
Of course, you'll get messages from their friends asking why you blocked said member (as if they don't know).
You wait until it is off the last three that have rated your profile. There is no size requirement to a stamp, so really the answer to your question is no.
And this would be better suited for an acolyte question since there is no discussion value in it. They'll be able to answer you directly.
