As for a weapon, I think they could benefit from some superior combat messaging on the melee side and maybe be ramped to super crap tier weapon accordingly. If they left a "stain" on a player & there clothes until they showered i hit - it would actually be a pretty cool way to -identify- people. As for any other stats effects, I don't think that's really balanced with the combat system but I could be incorrect about this.
I'm just a big fan of graffiti in general though and relish any/all ways to make corporate things less valuable or otherwise stained by mixer filth. Also, automated graffiti mural timed "bombs" that could be designed by a skilled artist then hidden in a room would be awesome. Bonus points if it makes people puke.
Of course, I don't imagine that many cameras will get tagged topside while it will be a struggle to keep cameras functional in the mix (as it should be). And it could promote RP. Did Joe's hood slip while he tagged the camera and did the operator see it? Go get Joe! Is it essential that a particular camera stay operational? Pay an Immy to check and clean it once a day!
Hell I could see a lot of low powered RP surrounding the cameras. Faction A pays three fairly new characters to maintain their network of cameras and disable their Faction B does the same. Now you have low level PCs going at each other.
I'm not saying that this is a great idea and I'm sure there are flaws in it but I would rather not see it dismissed so casually.
I saw someone mentioned that these shadow factions within the game of whom we can't OOCly call out on here could contribute further to the immigrant economy by giving them some solvent and paying them to go around and clean up their camera's. A crafty immigrant could get a hoodie, go around spraying their camera's, then be first in line to go clean them. On the other end of the spectrum, your mediocre solo team that couldn't afford EMP devices or deckers (Here's hopes to 3.0) could just whip out the low tech spray can and tag up that camera outside their targets hidey hole. I don't think it should kill audio, so it could be interesting how that could turn out.
Furthermore, if you spray a camera out topside, I think that should be an immediate indicator for the WJF to respond.
Good points discussed here in this idea. With that said, perhaps repeating "This idea is not good/similar methods exist/ etc" is not much of a contribution to the discussion (albeit sometimes needed).
Seriously though, +1 to tagging cameras. Back in my rebellious days (See: not that long ago at all) it was something we'd do just to get somewhere we couldn't be seen public drinking. It's more than themely, and even if there are countermeasures for cameras, there's countermeasures for a lot of things, but a THEMELY countermeasure is way more important.
