The only advantage that people have on spec is to notify if jungle camps have been taken but even so, jungle camps don't stay untouched for 3 minutes.

Status Kwoh already covered that topic. It may sound like a significant exploit but, in practice, there's no real impact - especially at higher level play. Still, the spectator team is on top of it and will make changes if necessary.

What about Teemo Shrooms?

I understand that the team is monitering this and will make appropriate changes if necessary. I don't understand why you think that those exploits do not have any real impact on the game. I am aware that at high level play, it is common to have some of the timers anyway, but this is not always the case.

I just found it funny that everyone is joking about "Lol specators on skype gonna cheat" when I feel that this is a very real possibility.

And I'm sure if do have some way, you're hardly going to reveal it here, but how will you know if people are abusing this or not?

Honestly I think you've somewhat missed the point. A vast majority of players who've expressed a concern over cheating were completely unaware of the existence of the 3-minute delay. This is in spite of the fact that, since our initial beta release of spectator, the delay has been repeatedly explained in FAQs, forum posts, live tournaments, and the recent spectator spotlight video. It's become somewhat of a running joke for players to bring up the concern without making any effort to investigate the issue.

I heard there was a 180 sec delay that is not even close to 3 minutes!!!!!! *rage*

So people are getting made fun of for not realizing there is a delay. I find it hard to understand how people could not realize there is a 3 minute delay, so I can understand why this would be funny.

Should I make a thread making fun of people who think a 3 minute delay is sufficent to prevent any form of cheating? I find it hard to understand how people could not realize that knowing exactly when the enemies buffs are going to be respawning without having to ward or use clairvoyance, and knowing when all of their wards have expired is an advantage.

EDIT: And if you want to argue that no one will bother doing this, you realize that go4lol and other prized tournaments are held on the regular client, where there is no way to restrict spectating?
