Anyone who seriously thinks you have any privacy online is delusional.
Anything you do online can be read or deciphered at will. If you think different then your only kidding yourself.
The NSA has the ability to crack any 256bit encrypted code in under 4 minutes. Believe it or not.
Re-mailers, IP spoofing, etc are all a waste. If they want to know who you are or what you said, it can be done.
Finally someone has brought up a subject that has plagued me for years. Up until now I thought I was the only one with this "problem"
I used to work security at a hospital and I used to complain to the other guards about the security monitors and the flicker. Unless I was looking directly at the monitor I could see the scan lines rolling down the screen. I would get some weird looks from the other guards when I would mention this.
Anyway, as far as CRTs go, If it's set below 85 hz I can not stand to look at it for more than a minute or so. I can even tell a difference between 85 and 100 hz easily. 100 hz seems perfect to me, anything less and I do get eye strain. I think it would be interesting for a University to do some sort of study and try to figure out if it relates to a persons mental abilities or not. IQ, Artistic ability, eye Rx, and other factors would probably play a role.
I have noticed that people that have a higher artistic ability or a higher IQ seem to notice this flicker more than those that don't. Maybe the reason in that lies more with observation skills. A person with an artistic ability tends to have better skills at observation by it's very nature while a person with little or no artistic skills seem to have less observation skills. The same is with IQ. A person with a high or above normal IQ tend to be more observant than a person with lower than average IQ. So maybe the mental capacity of the viewer converts into physical (vision) abilities as well.
Now with LCDs as others have mentioned are perfect. I can run an LCD at 60hz all day long and not notice one bit of flicker. However, the tech behind LCDs don't really compare as LCDs are more subjective to millisecond rating than refresh. From 25 to 8 milliseconds is the rating of most LCDs with the lower the ms the higher the "speed" of the LCD.
As far as conventional TV, I think the reason TV doesn't cause the eyestrain that a monitor does isn't because of the refresh rate but more of the fact that a TV screen is always "moving" How often does a TV station have a stationary picture on the screen? Unless you turn it on a 3 am (when they show the color bars) then 98% of the time the screen is moving. Also in this factor is the resolution. A TV's resolution is far below what a normal person runs their PC screen at. To sum it up, my feelings are the high resolution, stationary movement of a PC screen, factored with no motion blurring when something on a PC screen does move is the major factors causing flicker when viewed.
Maybe the people that suffer from flicker sensitivity should start a support group, the AFSV (Assoc of Flicker Sensitive Viewers) or something . I know I would join.
To see how "uncommon" the problem is, go into a Best Buy or CompUSA store and ask a sales clerk what the refresh ratings are on a selected CRT. EVERY time I have asked this from a clerk I get a glazed over look and a "uh, maybe the info is on the box" type of response. They look at me as odd when I tell them that to me a high refresh is much more important than a high resolution. Running a monitor at 1600x1200 is pointless if it runs at 70hz.
