whee this is amusing... I started by building a bunch of usless stuff to make the dsiplay... it didn't work right... I've fiddled arround. and now...
http://danwdm.da.funpic.org/other/greasemonkey/userscripts/gaiaBannerRedirectRemove.user.js
he eh... I ended up with a long script... removed usless things... and had to change some things because they didn't work... this final working version only has 3 actual lines of code...

oh ya... if you want to host it beside your own make sure to include in the instructions that popups half to be enabled for gaia... or else the warning dosen't work...
Options > Content > Allowed > Add gaiaonline.com
... and it works in a compleatly opposite way from yours... yours fixes links on every page... mine only affects the actual redirect page... so.. 2 different ways of making things work all dependant on what the user wants... no need to remove anything...
actualy... this is so opposite that the 3 lines of code don't even match yours.... even the url test is different from yours... lol...
oh ya... btw acording to the people in the Q&A... that do not click link in your sig is against the TOS...
