The community college has blocked the site in response to complaints about sluggish Internet speed on campus computers.
An investigation found that heavy traffic at MySpace.com was eating up too much bandwidth, said August Alfonso, the school's chief of information and technology. Forty percent of daily Internet traffic at the college involved the site, he said.
"This was more about us being able to offer Web-based instruction, and MySpace.com was slowing everything down," President Carlos Garcia said.
MySpace.com — a social networking hub with more 72 million members — allow users to post searchable profiles that can include photos of themselves and such details as where they live and what music they like.
Paul Martinez, 20, is a frequent visitor to MySpace.com and finds the site to be addictive. Restricting access to the site could be a good idea, he said.
"The library is pretty much full with people on MySpace, and with them banning it you won't have anything to distract you," he said.
Some though, disagree with Del Mar College's decision.
"We pay for school and the resources that are used," said Zeke Santos, 20. "It's our choice, we're the ones paying for our classes. If we pass or fail, it's up to us."
