I think this is one area of alt-photo that is absolutely hazardous to
its continued use in todays safety regulated society, even with its
groundswell. Once noted, we usually avoid telling anyone for fear of
reprisal. IMO, solving this problem could be the single most benificial
act one could do to for alt-photos' continued health.
Everyone talks about regulations but there seems to be little concrete
information available and we fear going to big-brother to ask for it.
