I don't know, I haven't even really been on dA in a while: I've pretty much have had nothing to contribute.
But it's funny... apparently someone out there is doing so-called "fan art" of ARTHUR characters in their underwear, and seemingly isn't getting called out on it... yet years ago, I do one humorous sketch of Jeanette in her underwear, and my arch nemesis blows the whole thing out of proportion and turns it into a controversy.
And I'm with you, there's a whole lot of way more disturbing things out there than just characters being drawn in their underwear.
But anyway, here's a new one: right now there's talk circulating around the fandom (even though it's mostly a joke and fluff) right now that Molly may actually be James's mother rather than his older sister. Theoretically, it's way too much of a stretch (I'm not saying it's impossible, but I doubt on a kid's show they'd have a character whose roughly 8-9 years old having a 3-4 year old son), but many have noticed that they don't seem to have a mother, James looks up to and mimicks Molly more than any normal younger sibling does, and Molly seems noticably act more like a caretaker/guardian to James than an older sibling.
Oh, and after getting to see "Buster and the Daredevils" again a while back, now I know why it seems strange that Slink suddenly and randomly became a Tough Customer later on... Slink goes to Mighty Mountain, not Lakewood Elementary. So somehow, I guess he must have transfered to Lakewood, and as such, no longer associates with Toby, and became a Tough Customer.
