[UA] Graffiti artists and a charging scheme

[Ja ke]

Is there an extant Adept school/avatar path/ritualised magic system that is 
heavily focused on street graffiti artists? (I don't have statosphere or 
PoMoMa yet, and as I once almost reinvented irascimancy I thought I'd check)

Oh and while I'm at it, does this seem like a decent charging structure for 
a racial stereotype based magick school to you peeps? (is the sig too 
difficult/too hard to portray and work within the gaming system?):

Paradox: You gain power enforcing a negative stereotype that isn't really 
representative of either you or your ethnic group, and empower yourself 
while at the same time negatively affecting your community.

Generate minor charge: Cause someone to make a stress check or set off a 
persons passion stimuli in a way that reinforces in that person's mind your 
chosen negative stereotype.

Generate a Significant charge: Cause someone to become a racist or 
discriminate against your 'kind of people' who didn't before hand.

Generate a major: be the direct cause of an entire large community attacking 
or ostracising 'your type of people' in such a way that it causes many of 
the affected group to die or be killed.

Taboo: A Playa taboos whenever someone challenges their behaviour in someway 
and gets away with it and also when they are seen acting in a manner that 
doesn't fit the stereotype they are supposed to be portraying
