Twitter spam?

Spam is starting to become a real problem on Twitter.

So many brands have jumped onboard and set up automated replies to tweets that contain references to the brand.

I find this highly annoying. I suspect I'm not alone in this.

Today's piece of Twitter spam is particularly weird.

I posted that I was culling a few live tracks by the Rolling Stones from my iTunes.

Moments later I had a reply from someone purporting to be a Stones fan.

Like most people sucked in by spam I clicked on a link.

My clever Macbook told me it wasn't such a good idea to have clicked on the link.

As you can see from the pic above I wasn't the only person to get this piece of spam.

Which as I said before is becoming a real problem. But what can we do about it?

And more importantly what are Twitter doing about it?
