Will Spam and Porn ruin Tumblr's Reputation?

It's somewhat ironic that spam and porn are never cited when someone quotes their vanity metrics, e.g.: http://mashable.com/2011/08/31/tumblr-record-uniques/

If anything, I think the special brand of "tumblr porn" has differentiated it from other blogging platforms.

"Users are getting worried about spams and malware spreading at a constant rate in Tumblr."

Really? I've used Tumblr every day for a couple years now. I have never seen any "spams" or porn. This user isn't "worried."

No.

Pithy, but I usually answer headlines framed as a question "No". If evidence was present or the idea cogent then no question is required.

"I'm simply asking questions" - an intellectually lazy way of implanting an idea.

spam and porn are part and parcel of any successful website
