How many keys can you activate daily?

Duplicate keys will also contribute toward this limit

Was this not proven to be any activation attempts valid or otherwise, I know I've been locked out after buying a number of bundles to catch up and trying to activate everything back to back.

That would mean that whilst there's technically no direct daily limit you'd still only be able to activate so many keys during any given "daily" period"

Actually i faced that thing when you activate too much correct keys aswell, i was filling in my humble bundle + groupees bundle and it said i have to chill out after like 10-20 keys in short period of time.

50 key limit, tested by myself last month.

Someone asked the same question, and I actually counted all of the keys I activated.

Awesome, thanks! I'm also doing some cleaning and I expect to add about 50 keys.

Pretty sure it's around 10?

Invalid? No more than 10.
