For anyone who's interested, not many important changes aside from the fact that Reddit is now kindly asking it's users to go through arbitration when they have a complaint about the DPF
I don't know if it has any legal value, but here's what I've been doing with online services that really matter (not Reddit, I don't give a shit about Reddit, but things like my bank):
I read the TOS - which, in the case of actual serious online services, tends to be shorter - and I make a note of anything I don't like in it. Then I click agree, then I send an email to info@, support@, legal@, webmaster@ and whatever other vaguely relevant email I can find in the TOS' issuer's domain telling them this:
"I clicked okay because I needed to do XYZ and there was no button to discuss your terms or disagree. But I disagree with the following points. Here are my counter-conditions:
[...]
If you disagree with my conditions, please send me or my lawyer - who is copied on this email - your counter-proposal within 1 (one) week. If you do not sent me or my lawyer an email within 1 (one) week, I shall consider my conditions accepted, legally binding and superseding the relevant sections of your original TOS."
And I copy my lawyer.
I've never gotten any reply, because no actual human reads those email addresses. If anything comes up, I'll pull the counter-email I sent them with my conditions, which they agreed to by not answering. I've never had to use them, but I really wish I'll get the opportunity to test them in court some day, just for shits and giggles.
And yes, I have enough disposable to pay a lawyer to do this kind of shit. I'm a spiteful man when it comes to tech companies, and I'm quite ready to bankrupt myself to fuck them in the ass.
Sending an email saying you dont agree to a document you signed. That does not nullify the contract. If it actually went to court, it would get tossed and the original terms would be enforced.
