Well since I'm on my phone at work and I'd rather save yourself the atrocities, I'll just mention the TWO defunct webcomics on Captainn.net Haven't been to the site in ages, most of it's gone now last time I checked. But man when I think bad webcomics, three are the first that come to my mind (aside from the popular targets like CAD and VG Cats)
First one was a terrible sprite comic about a bunch of random kids going to video land. It's pretty straight forward for the first few strips, but then it just devolves into some kind of random story that makes NO SENSE whatsoever. I want to think it's some kind of RP done between the site owner and his friends with a bunch of winks, and nods and in-jokes but the problem was it was just terrible. Not to mention the piss poor English (I'd give it a break if the site owner and creator wasn't a native English speaker, but he was). He had a strange obsession with saying things like "You stop now"
Second one was a much more shorter "doujinshi". What burns me about this one is that it's an actual re-imagining of the Captain N cartoon with a couple of neat ideas, but everything else about it sucks. Blander than shit artstyle with terrible depictions of the cast where the artist/author went absolutely bonkers with the shipping.
Seems silly to sound so butthurt about something based off of Captain N of all things, but eh, I have a soft spot for him and it really is terrible. I'm surprised it's not mentioned in that Bad Webcomic Wiki linked in the first page.
