This is the wrong attitude to have. You shouldn't be stopping an ally from farming; It's fine to proxy your own lane, as long as it's known by your team and all of the affected parties (ally parties) agree to the proxy. The mid laner said to stop, which meant stop. Listening and cooperating with your teammates is essential.
Why does the ally need to agree to your own proxy?
I mean it's your lane and as long as you play it properly and don't feed there is nothing to say about it.
Allies agreeing, as in the example above -- he's proxying an ally's lane, they don't agree, he shouldn't do it.
Allies agreeing, as in a jungler staying top side most of the game for counter-ganks, stopping aggression top side as you leave or meet them, etc etc.
Edit: was a simple precautionary suggestion, to help with team communication and such.
no, if singed is proxying base then he gets to choose, because with balls like those he wears the pants in the relationship.
With balls like that he'd probaly need a kilt though.
Let's give him a denim kilt and call it Scottish jeans.
Nah b, that's not how it works. If he's in the base, he's alone. His team has to understand that there will be no aggression top lane and that their top laner has free roam throughout the map if they choose to roam. If he's proxying his own lane, (copied from comment below this) "Allies agreeing, as in the example above -- he's proxying an ally's lane, they don't agree, he shouldn't do it.

Singed has to cooperate with his team; can't simply ignore the rest of the team and leave it a 4v5, 4v4, etc.
If the enemy ignores singed. singed wins the game. singed literally wins top and mid by doing this strat, even if the mid constantly dies guess what, they can't push.
Singed isn't leaving the game 4v4 or 4v5 though, the enemy team is going to try and stop him. realistically any player that isn't literally retarded will try to stop him because if they don't singed solo wins two lanes. If you don't understand this then clearly you are uninformed enough to not deserve a voiced opinion.
If I was the mid laner I'd be a bit annoyed too.
