I can understand the fear and paranoia but there are simple concepts to understand.
Tracking cookies are used by advertisers (and who knows who else) but they are also used to obtain and keep a profile at the sites you visit regularly. Unless you want to log in manually every time you visit a website, cookies are something of a must. However, most browsers let you disable cookies if you so choose.
Programs also exist to mask your IP address or hide anonymity behind a firewall. If you’re paranoid or extra security conscious, you can hide behind those as well.
Finally, no matter what technology is out there, somebody who wants badly enough to get your data can get it. Don’t type things on the internet you wouldn’t admit to in public - especially at your place of business. The business owner has every right to monitor your e-mails, web traffic and tweets done at the workplace so if you think a site might be objectionable to your bosses (including Free Republic), don’t go there.
For the record, my last two employers I have refrained from visiting FR at the workplace because I’m not completely sure but that there could be some form of retribution over it. Both employers are rather fond of Bambi but I needed the job after being unemployed for a year.
IOW, be smart and don’t post what you don’t want in the public domain.
Very informative and useful comment. Thank you.
