Tricking is indeed illegal on .net, but there is a difference between bribing and tricking.
I read bribing as:
I'll give you 50K each resource if you pass me the contents of your tribes forum.
or
If you attack this tribemate of yours, I'll let you keep 5 of the villages.
Tricking however, would be:
If you restart, I'll send you 5000 of each resource. Without any intention of doing that.
The difference is in the (potential) harm to the player (victim) and the intention of the 'trickster' (briber). Sending someone the entire contents of a forum isn't directly harmful, it happens anyway with spying. Promising to help someone betray their tribe is perfectly allowed as well, happens all the time in wars. Making someone who doesn't know left from right in the game restart from nothing on a false promise, is a lot more harmful.
