"The computer you are using no longer has access"

How can I do this properly?

Long story, so I won't bother with HOW it came up, but I'm intrigued by the fact I tried to login to a site but was told that my "computer" had tried too many times to login unsuccessfully and I should use a different computer.

Banks etc. simply lock the account - 'which computer' does not matter.

I cleared my cache, history, cookies and refreshed to a new IP address with my ISP - still I got the message "The computer you are using no ..."

I'm intrigued, as I have a voting system on my site that simply uses IP addresses to block people from repeatedly voting within a 48 hour period. Not much help if they've got a freebie proxy IP rotator.

What coding tells you which "computer" is trying to login/vote?

Google

"three ways sites can track visitors without cookies"

Nope. Changed IP address, user agent and browser ... "The computer you are using no longer ..."

Whatever they are using, it appears to be able to see my computer! Can it see me? I hope not ... my hair is such a state! ;)

I just plugged in a Windows laptop and logged in fine. No matter what I do to my Mac computer, it won't log in today when it did yesterday.

Okay how did you change your IP?

You may have changed your computer's IP, but did you change the IP assigned to your modem/router by your ISP?

It may be a flash cookie, also known as LSO's. They are not stored in your regular cookies folder and do not get deleted when you empty your cookies folder. I'm not 100% sure but they may not be browser specific either so maybe that's why they followed you across browsers. There's a good Firefox add-on called "better privacy" that can squish it.

Okay how did you change your IP?

There's a button on my router to change the IP address. When I press it, the number that appears on any "what's my IP" website changes. Is that not changing my IP?

Holy crap! I had no idea these existed! That seems to be it though - went to the Global Settings at the Macromedia site, deleted all the rubbish stored on my computer and ... bingo.

Thankyou!

Right, that should have changed the IP, just checking. As for LSO's, look into the Better Privacy Firefox plugin [addons.mozilla.org], I really like it.
