Where are any?
If you look at other games that are more or even less popular than Evony you see a ton of bots or methods of cheating but here for Evony there's nothing. Evobot was the biggest attempt at it and it's been dissolved out of fear. Even though I don't consider click macros to be true bots, there's still ESB. Haven't been able to even try whatever they want to call their "bot" at vx0, if it even is one so I can't add it to the list.
All in all, where are the bots? It most certainly is not difficult to get even the most minor proxy setup for Evony. If you know Java or even C# then your job is 100x easier and if you know Flash you have everything you need right at your fingertips. Hell, you can even make an Evony bot out of PHP.
