Anti-Obama Bloggers Say They Were Silenced

Web loggers who are campaigning against Senator Obama's presidential run are accusing Google and Obama supporters of silencing them after their Web logs were marked as spam and their accounts temporarily frozen.

On Thursday, hours after publishing a post about an online petition demanding that Mr. Obama publicly produce his birth certificate, an associate professor of business administration at Brooklyn College, Mitchell Langbert, found that he could no longer access his Web log.

Google's Blogger hosting service had suspended "Mitchell Langbert's Blog," which Mr. Langbert describes as "two-thirds academic stuff I'm working on and one-third politics," until it could verify the Web log was not a "spam blog," or a site designed solely to increase the page views of associated Web sites.

A day later Google lifted the block on the account, but the incident and earlier Web log freezes in late June have led Mr. Langbert and other anti-Obama bloggers to accuse the Illinois senator's supporters of intentionally identifying their blog addresses to Google as spam blogs. They also say the company has reflexively suspended the sites.

"These tech-savvy smart alecks have figured out that if you report a blog you don't like, you can do some damage to a person," Mr. Langbert said.

A spokesman for Google, Adam Kovacevich, said in a statement that an overzealous antispam filter was responsible for the blocks.
