Got here late and missed your joke, but I can put together what you did. I will say that generally stealing avatar photos is not nice. But if some girl wanted to look seductively sexy, I could understand them stealing yours. :-)
If it was a picture with me in it, or people that I know, then I would not be too happy and find it rather creepy! If it was a picture with no people in it (like say landscape or scenery), then I would think it very cheeky for someone to just use that picture without asking, but it wouldn't bother me too much. I guess the less personal the picture, the less it would bother me! :)
well according to google analytics, 9 out of 10 women who visit my profile download my profile picture to their hard drive. What they do with that picture when no one is looking is anybody's guess, but i imagine if a few of them (or guys) used my photo in this way, it would be because they see me as either a source of inspiration to work up to, or a source of sexual gratification that only my face can provide. In either circumstance, I consider it fair use
If it was a picture of myself I'll be pretty mad cause they're saying stuff using my image which can get me in trouble depending on what they're saying. If it's a picture from the Internet, like I have now, I wouldn't care too much.
Nope. It's my Immortal Technique T-shirt, they're more than welcome to. Same if they used my Free Palestine T-shirt that's my cover image. They can even use my status thing by just writing a sign saying Free Mumia and use that too. No problem whatsoever with me.
