    - Your IP.

    - From your IP, location information, sometimes down to city level, sometimes not. Sometimes there is even more information, e.g. if you are accessing the Internet from a University campus. The ISP will usually know the identity of the user, but that is only available to law enforcement.

    - From the accept-language header, user language(s) that have been set in the browser. This is freely manipulable by the user (i.e. you can't trust this information, especially in the context of an attack.)

    - From your user agent string, the browser version, possibly some of the installed extensions, and the operating system. This is freely manipulable.

    - From the accept: header, sometimes information about installed programs, although this is not very reliable. This is also freely manipulable.

    - From making a JavaScript call - your local time on your computer, your screen resolution, possibly more information about installed plugins like Java and Flash. Freely manipulable.

    - From making a HTML 5 geolocation request in the browser - the geographical location of the user as determined by GPS, WLAN, or other means. Needs the user's consent and is freely manipulable.

    All hackavelli said is correct, with the comment that you could use a high anonymity proxy or vpn to change the ip address the site sees in the access logs. You could use a freely available tool such as the NoScript freeware plugin for FF to ensure that no script that could retrieve more information about your computer is allowed to run on your computer. The MAC address can be seen only in the local network environment, so you needn't worry about that.

    Thank you, everyone! I wanted to give this a bump because I had a (probably stupid) question.

    I heard from another SEO guy that Yelp gathers your IP address, MAC ID number, screen size etc. If I'm looking to post reviews and am using a VPN, the IP address issue is covered, but what about any other alerters? AKA MAC Id etc?

    I know you really have to monitor any and all accounts...add friends, actively post reviews, actively participate on forums etc to be safe from filtering as well.

    Also, here's a big FU to the yelp filter anyway.

    They collect 15 things like screen resolution, user agent etc.

    they only use it to link suspected multiple fake accounts.
