Anderson, who left the venture in 2009, described the website as a "cesspool that no-one wants to visit" and raised concerns that Google+ could become the same unless appropriate policing is maintained.
The censorship debate began when TechCrunch columnist MG Siegler criticised Google for removing his Google+ profile picture without prior warning. The image, which depicted him with a raised middle finger, was deemed offensive by the platform holder.
"My problem isn't so much with the fact that I couldn't have a profile picture of myself giving everyone the finger - which I can and do on Twitter and elsewhere - it's that no-one bothered to tell me or warn me before they just went into my account and deleted the picture," Siegler wrote on his blog. "What if this was the only place I had stored the picture?"
Anderson responded via his Google+ account, backing the search engine giant's decision to censor the photograph.
"I would respectfully submit that we, the users of Google+ (and Facebook or Twitter) don't need to see you flipping us off, nor do we need to see you naked, or displaying something else generally considered offensive," he said.
"When a social network [lets] that stuff slide, it turns into a cesspool that no-one wants to visit... sorta like MySpace was."
Anderson previously criticised MySpace via his Facebook account, explaining that he no longer has a profile on the site because he is "not a fan of what the new folks have done" with it.
Google+ opened up to the public in September. Recent estimates suggest that the service could surpass 400 million users by the end of 2012.
