Dusty Revenge:Co-Op Edition was revoked, anyone else? [TremorGames revoked games]

They could just transfer 100EUR normal way and then once Tremor points have been gathered refund the transaction on Paypal claiming you did not receive what was promised. Easy peasy.

While arguable does mean 'able to be argued' in a phrase like 'Well, that's an arguable point.', for the usage you applied it to, I believe it always applies the meaning which is synonymous with 'doubtful'- ie, able to be argued against. Maybe it's a dialectal preference, but either way, it definitely confused me about your intent for a good moment [if for no other reason than that I use arguable quite a bit myself, in the manner I just indicated]. :'P

Well, I suppose quantity could be a factor to an operation like that. I suppose if they just filtered out any (eg, < 10 copies) accounts from their tests, they'd have had a strong buffer by which to remove anyone that couldn't reasonably argue personal use, without risking offending more normal users utilizing the trade-in option that TG appears to have.

On the other hand, I thought Humble limited purchase per account to 3 copies, which is what has me confused. I wouldn't have thought TG would have been able to acquire so many bundles off of, say, 2 accounts. Humble's own purchase protections should have hindered their efforts to determine such matters.

First off, I don't believe Humble legally qualifies as a charity in any way. What legal benefits they get from their charitable donations, if any, I don't know, but the end effect shouldn't change their legal standing for these matters. Second, you actually can't legally consider anything a charitable donation if you obtain meaningful recompense for the donation, so there is no effect from the perspective of consumer purchase.

Keep in mind also that EU laws don't function the same way as State laws, which are what I'm referring to. Given that EU laws far more heavily favor consumers than US laws, it seems unlikely that it wouldn't have been even more difficult for Humble to have affected any response outside of courts.
Likewise note that Humble is based in San Francisco. As a US business, United States laws would be the only ones that would apply when purchasing from it, unless Humble has an established legal presence within the EU.

Can I get an invoice or tax receipt for my purchases? 
Our Terms of Service state that our service is only for the sales of products and product rights to customers for their personal, non-commercial use.  As a result, we do not have any setup for providing business invoices or receipts for business purchases.
Humble Bundle is a commercial business and is not considered a 501(c) Organization aka a Non-profit organization.  Purchases of bundles do not qualify for tax deductions under current tax laws for most countries. For more information, please click here.

I don't know why so many people always assume Humble is an NPO when they clearly show their 💵cut in every bundle slider thingy. Think of it like a $ charity can at the supermarket checkout register. You're still buying products and the supermart is still making money, they just take your $1 and use it to get a tax write-off by donating it to whatever charity it is. Since it counts as them making the donation and not you. Hopefully that makes sense.
