This scheme could be implemented more cleanly by using
a
cookie rather than a separate domain. A person visiting the
donate page could find a link to set a cookie that says
'ads=true'. After that, they would see ads until they turned
them off. Alternatively, this could be an option in user
preferences.
Easiest yet: serve all the obnoxious ads you want, just serve them all from another
subdomain; eg,
inyoface.wikipedia.com. Doing so would encourage the adoption of filtering
proxies or browsers that implement easy image- and flash- blocking.
(This suggestion is close-smilied for the humor-impaired.)
