As the Facebook-ignited campaign “Everybody Draw Muhammad Day” arrived today, Pakistan expanded its Internet ban to include YouTube.

“Everybody Draw Mohammed Day” took off within days of Norris’ April post and a subsequent appearance on “The Dave Ross Show” she says she also regrets. Thousands of images have already appeared on at least two related Facebook pages she did not create that boasted upwards of 71,000 members Thursday afternoon and features not discussion or debate but streams of verbal and visual vitriol.

Depiction of any prophet is prohibited in Islam, a cultural tenet that led to riots, religious tension and even deaths after European papers published cartoons featuring Islam’s chief prophet in 2006.

A Pakistan Telecommunications Authority (PTA) says the decision to block YouTube was made after government monitors discovered that references to the primary “Everybody Draw Mohammed Day!” Facebook page–which now has more than 80,000 “supporters”–were growing on the video-sharing site.

The page, which Jon Wellington told Comic Riffs he started in a “whimsical and nonjudgmental spirit” last month, quickly became a forum for a hate-laced war of word and image, as both pro-Muslim and anti-Muslim posters often spewed vitriol.

The campaign also spawned an “Against Everybody Draw Mohammed Day” page, which as of Thursday has nearly 100,000 supporters who “like” the page. Molly Norris, the Seattle cartoonist whose posterlike illustration titled “Everybody Draw Mohammed Day!” last month spawned the protest, has herself joined the “Against” page.

“I will not be drawing Mohammed on May 20,” Norris told Comic Riffs on Wednesday. “I joined ‘Against Everybody Draw Mohammed Day’ and folks from there write to me. I never even set up a place where people could send images to. Other people started Facebook pages for this day but I never did.”

Islam is the majority religion in Pakistan. Some Muslims consider any depiction of Muhammad to be blasphemous.

“We are an Islamic republic, so we are monitoring the Muslim content,” said the PTA spokesman, Khurran Mehran.

The Post’s Brulliard reports that Wikipedia also seems to be blocked today in Pakistan–though it wasn’t immediately known whether this was because the government banned access. The cellphone company Mobilink said access from smartphones to Facebook, YouTube and other sites with “blasphemous content” were also blocked.
