Replying to Protecting Icons

Okay, so every couple of weeks I see that some person with 30 posts has my icon and it drives me completely insane. I like my icon because its unique and stands out from the rest of the crowd. Besides some other members who have ski gifs similar to mine as their icons.
But this has been happening ever since I started going on ns. Back then like 15 people had the flashy neon saga icon.
On this site, your icon is your identity pretty much. Everybody knows that ribbs is the boob icon guy. 1337 has the mudkips in his. El.gato has the cat with a helmet and so on..
The point is, I feel like we should be able to keep our icons without having to see somebody else with the same one a few weeks later.

So is there anything that the admins can do to prevent this from happening? Can we make it so a member can't rightclick and save a person's icon to use as their own? Or something along those lines?
I hope that made sense, I'm not great at describing things lol.
And idk if it's a big deal to anybody else but it's just one pet peeve I have about this site.

Thanks.
