how it works is intentionally vague and fluid.
once upon a time these things were called 1x1 gifs or transparent gifs or invisible gifs...
basically single pixel 'files' downloaded onto yer machine when an image was viewed/opened.
((scan your pictures folder or downloads/images file and u may have 1000s of 1x1s))
those still exist (especially in windoz) but the process is a lot more sophisticated now.
COOKIE is such a non threatening word/concept and who doesn't like cookies?
while web beacon or web BUG begin to read more ominously.
we do get at least ONE cookie from arf, related to log in, IF you check the "remember me" box.
years ago that "remember me" box was DEFAULT SET TO ON...
i asked/suggested it be change to DEFAULT OFF and this tweak was quickly done.
so don't USE auto log in/remember me and u won't get this memory cookie here.
the ads HERE are generated by guuuuugle.
so guuuuuugle uses cleaver surveillance tools and since arf is a "partner site", guuuuugle tweaks the ads u see.
for example we might ALL see ads (top or side) related to a specific topic title...
right now eye am cn cell phone spying and pop up blocker and spy camera ads along with the usual a/s crap.
the stronger the thread title the more specific these ads become.
they ALSO get tweaked individually based on IF guuuuugle has been tracking your browser activity.
yahoo does this too.
in days past one needed to CLICK on an ad, now all that's needed is to ROLL OVER some ads with da'curser.
and bam u gotz cookies AND bugz.
all the major browsers have tweaks to impede this stuff
at least temporarily.
for example YOU can choose WHICH cooks' to allow and which to block.
and many of the browsers have wayz to flush this crap out temporarily
yahoo even has a TRACKING COOKIE u can accept that BLOCKS tracking cookies...
depending on platform there are free OR $ programs that also clean up or block cooks.
while typing this i ran me'scanner app and found 7 trackers...
cnn, a local newspaper and 5 hits for google ad services (used by partner sites, like THIS ONE)
the google partner sites (like this one) feed/use the google LABLED bugs,
yet they can CLAIM not to do this stuff (blame it on guuugle right?)
didn't nixon refine the notion of "plausible denial" for us?
what we DO HAVE here is just as interesting mehbe ...
so ken u wouldn' happened to be using ie8 and windoz7 would ya???
see along with the beacons and bugs this site actually DISPLAYS who just logged in and a bunch of info...
scan to the BOTTOM of any of these forum pages and CLICK on the blue globe/impulse thingie....
