Hm. Do you really want to do that on your own? You'd have to find the ToS, document ToS changes, analyse the ToS, etc.

We're trying to do that already at http://tosdr.org, please join in (http://github.com/tosdr) and http://tosback.org

Edit: Hm I thought 5apps supported https already, i guess i was wrong

Hmmm...

You attempted to reach tosdr.org, but instead you actually reached a server identifying itself as *.5apps.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of tosdr.org.

I'm guessing you have HTTPS Everywhere installed. It works fine on HTTP.

That sounds great. The only problem is that you just have to accept the word of whatever PR person you talk to at these companies. Not that I really expect them to flat out lie to you, but I wouldn't necessarily expect the whole and complete truth either.

Are data retention policies generally in a site's TOS?

Not that that'd be much better than a PR rep, but it'd be easier to get at least.

I would monetarily support that.
