The Clone Wars suck
The Star Wars fanbase seems to be divided about the Clone Wars CGI cartoon series. While some praise the show for its storytelling, its action and the usual stuff that TV shows get praised for, others just can't stand the "kiddy-fied" tone of the series, as well as such abominations as Ahsoka Tano, the Lurmen and, dear God, the recurring appearances of Jar Jar Binks. On Darthipedia, these negative aspects are emphasized, and are shown as reasons why the Clone Wars cartoon RUINED Star Wars FOREVER. By the way, we can also infer that Dave Filoni is a sherbert.
Over time, however, the Clone Wars cartoon seems to have gotten better (correcting most or all of the above problems, even Jar Jar's recurring appearances), with Darthipedians and their articles reacting accordingly.
Jar Jar Binks is easily the most hated character in the entire Star Wars universe. It therefore made sense for him to become one of the prime targets of satire on Darthipedia. However, since everyone is a Darth (see below), Jar Jar Binks became the sinister Sith Lord Darth Darth Binks and the website's mascot.

Darthipedia features lots of articles about characters from properties other than Star Wars depicted as humorously exaggerated Star Wars characters. The prime targets for this seem to be the various Muppet characters from The Muppet Show and Sesame Street, which are portrayed as members of the Puppet species. This may have been due to the fact that both shows had a crossover with Star Wars at one point; someone must have thought about how ridiculous the Muppet characters would have been as "serious" Star Wars characters. These crossovers are even acknowledged on this wiki, and "Dearth Nadir" has his own article.
Wookiee-Nookie is a particularly painful form of relations, usually performed by a Wookiee or other furry alien, that seems to kill the other creature involved in the act. The accompanying image, intentionally designed to be disturbing, depicts a proper Wookiee-Nookie as performed by Wookiee Goldberg on Cassus Fett.
