Notices from the Universal legal department have popped up for some CafePress Browncoats, and they're not all cease and desist orders. CP is aware of this and at the moment, searches at CP for "firefly" or "serenity" bring up 0 results. Odds are good that with the recent growth in licensed versy stuff the legal people are cracking down more, possibly at urging from the license holders. Dunno.
But that means it's time to check again and make sure you're not using any official logos, character or ship likenesses, reproductions of movie graphics, or other potential copyright infringements. You shouldn't be anyway, per CafePress' own rules, but still.
Also not a good time to yell at them. Won't do any good, and might make things worse. Remember, Universal has every right to protect their intellectual property and they have a duty, as they see it, to protect the interests of companies that have paid hefty fees to make official products.
Although it would be really interesting, just for fun, to tally up how much each of us has worked, hour by hour, year by year, to promote increased awareness and sales of their intellectual property. Maybe submit a bill for PR and marketing services rendered.
Edited to add: I've trimmed some of my CafePress listings here already. If your site is linked on SerenityStuff and you'd like to lay low for awhile (or disappear completely), please let me know and I'll pull it.
