it's not because the con is bad, it's because the people involved around artist alley (not the artists) are a bit 'ignorant' about etiquette, and the problem is how the artists behind the tables deal with it or ignore it that make it worse. No, you don't tell them to go away, but yes, there are ways to deal with it, or prevent problems entirely.
Can you please elaborate on what you mean here? I think this forum is fine to give some details. Are you speaking about etiquette between the artists and the consumers? Are you talking about the staff and artists? As a fan of artists alley I would be VERY interested in hearing about any expected "etiquette" before I break any rules. Thanks!
Actually...excellent question on this too! Yes, because the staff of Fanime aren't consisted primarily of artists (who are in charge of the con and not just the illustrations, which I mean), they don't have much influence on the rules. And I doubt even having them would do anything, if no one understands WHY it shouldn't happen!
so here's one example: I know one really big hidden issue that only pops up if you're aware you've been a professional illustrator or experienced stuff like plagarism or things like memes that are related, one rule that congoers always break is taking out their smartphone, zooming in on your artwork, and *click* and walk away. That is a no-no, and even if they think you're a poop for not letting them take photos, they're a poop to even try that in the first place. Unless they give you a name, photograph you in the photo, and hopefully email it back to you, it's highly disrespectful.
artist-to-artist etiquette: I don't see how Fanime doesn't catch some of the art thieves around the place (not just artist alley but at the dealers hall too). A semi-decent artist can easily see if the work was scanned and poorly printed on the surface of other objects like buttons. If you see it, even if you like it, don't buy it. The person selling doesn't deserve that kind of attention. I don't think staff has a way of dealing with this, since I see it at multiple conventions, all the time.
Between artist and staff/con-goers? I think the staff should have a stash of emergency waterbottles for anyone who feints/nearly passes out behind artist alley-it's most common for noobs behind tables because of dehydration. If you see someone really exhausted a few hours before the con, you may want to just ask them if they ate/drank anything, and advise them to go get a drink (dude there's a water fountain conveniently set at Fanime inside that room). Very simple, but the moment you see someone sitting next to you feint, barely move, or find out they couldn't even get out of bed for a few hours the next day, it's incredibly likely it's dehydration and not because they're tired. That or their ego was crushed behind the table, which I will explain in the panel as well (I mean, if I DO get this panel)
and finally, don't spit/eat food in front of their tables and lean in, it's disgusting.
much more discussion in the panel.
