What can cause an abandon?

Question

After playing a couple of games yesterday, my abandon rate went from 0% to 1%. Yet I didn't abandon/rage/disconnect any game. And haven't done so in any of my games.

I did have a game that aborted because someone else failed to load before getting to hero selection. But I've had that happen before and never received an abandon. And I know I was loaded because I was chatting with others while waiting for loaders.

Answer 1

You recieve an abandon if :

• You disconnect from the game and fail to reconnect within 5 minutes (given that the game keeps on playing, if the game is paused, the 5 min are not ticking)
• You disconnect from the game and explicitly click the "Leave Game" button (in the matchmaking menu)
• You spend more than 5 min in the game without earning any experience (the game then conciders you AFK and give you an abandon)
• You have not interacted with the game in the last 2 minutes

You used to recieve a "secondary abandonment" if one of the member in your party abandoned the game (following one of the condition listed above). Those were displayed between bracket in your DotA profile :

Abandon : number of abandon (number of secondary abandonment)

But since one of the last patch they are no longer counted and you just have a global % of game abandonned in your profile.
