Dota 2

a virus has taken over. it sends free copies and when people accept the gifts, their steam gets a cold and starts sneezing other dotas :(

Gabe's trolling.

I'm not.

Because Valve likes to dump shit in people's inventories?

They want to get lots of people playing the beta (I would have said stress-testing, but doubt they need to do that). The thing is though, they've released so many copies into the system that they may as well open it up as either an open beta or full release - all that DoTA 2 is now, is spam.
