It is. Linking to an episode on Youtube or whatever video site you might find one on, with the exception of the official ones on iTunes and similar is technically piracy. Which gets you a grey name timeout.
Things got a bit lax earlier in the threads, which is why episode links got away with it.
The old rules were that any evidence of
video game piracy meant a ban (although piracy witch hunts were also banned, because deliberately trying to get someone banned was bannable), not because piracy was bad, but as a concession to video game industry insiders on the forum. Non-gaming piracy seemed to be ignored because the forum didn't have any particular stance for/against general piracy.
The anti-piracy side often complained that this policy didn't go far enough and was a double standard, and the RIAA/MPAA started getting scary with going after "enablers", and for whatever other reasons Evilore seemed to extend the anti piracy policy to all forms of piracy.
Late last year he sort of warned PonyGAF that while it wasn't his job to play copyright police, he had some moral reservations about Youtube piracy. Although at this time, Hasbro wasn't taking down Youtube links, Pony-haters were, and Hasbro's ire was directed solely at the Pony-haters who were impersonating them, not the Youtube uploaders. So I felt there was no moral issue where MLP was concerned.
Since then, NeoGAF's anti-piracy stance seems to have solidified, and Hasbro started cracking down on Youtube, apparently as an obligation after they sold the North American DVD rights to Shout Factory, who still hasn't really done anything with them.
So I don't think PonyGAF was really "lax" about piracy and Youtube links, but the rules and morals shifted around a bit.
And just to throw it out there, I think Bronies are a prime example of a company
benefiting from widespread piracy, assuming Hasbro can ever figure out how to cash in on Bronies.
What kind of little fan nods / fan service would you guys like to see in Season 3 (a character like Trixie returning, a popular BG pony getting a voice and/or more screentime, a Scootaloo episode, etc), and what kind of things would make you throw your arms up and say "I'm out, this show has clearly jumped the shark!"?
A Scootaloo episode isn't fanservice, it's a regular part of MLP that has been somewhat ignored because no particular writer has yet come up with a good idea for an episode, or at least not one that's better than whatever other idea they have in their head. I'm sure we'll get one sooner or later.
To your question, I'd be fine with an entire episode centered around Lyra and Bon Bon as lesbians (tastefully done, not "We're lesbians! for the sake of it), with Derpy and Octavia and DJ Pon3 (and yes, they can call her DJ Pon3) in supporting-cast roles. If the writers are inspired to do something that fits with the series, I say go nuts.
I think fanservice would cross the line as soon as it requires the audience to read any particular piece of fanfiction to truly "get it". I think the show shouldn't reference any one specific piece of fan-work. The only direct fan-interaction should maybe be a contest winner or something.
