The issue:

People keep anchoring ESS inside anomalies, and exploit the game mechanisms to provide their ess with "defending rats", and hard to navigate structures.

It is very easy for the defender to just warp to the ESS with an implantless pod, but it is very hard for the lucrative pirate to steal from them.
Small ships cannot tank the rats, bigger ships are too slow to travel the 30-60 jump distances.
finally, fighting players AND rats at the same time is not really pvp either.

Suggestions:
Prevent anchoring of ESS in anomalies
increase ESS pay out to compensate for the increased risk

I do not dissagree at all, but you guys are missing the key point.

The whole point is that ESS should encourage pvp

There is no doubt that players will always find ways "around" things, and then other players will adapt to that.
ESS is an ok source of income for pirates, and many times also an interesting activity, especially when you have people actually responding, and trying to kill you. Having an ess inside an anomally will not prevent an experienced pirate to steal from it, but it will reduce (prevent) any chance of pvp from happening.
The defenders will usually warp in an implantless pod to share, or use a stupid strong ship and ignore the rats, or even simply ignore the pirate "because the rats will kill him".
On the other hand, the attacker can simply risk and hope to get lucky or wait and react to the defenders, but in most cases he will not engage the enemy. Why? because there is no point in engaging a ship 2 classes bigger or even to try and shoot a pod if the anomally is hard enought and could pop you before you can warp out with your ship intact.

Ofcourse, you can go after ess-in-anomalies with a bigger ship like a t3, if you dont mind the stupid-long time it takes to travel 30-60 jumps in hostile space (or if you have a usefull wormhole), you can team up with others, you can lurk in the shadows, time and schedule your "raid", seek empty systems and a ton of other different things.
But will you actually pvp against someone who could have been a challenge inside an anomally? Will it mater if the system has a similar amount of players (eg 1v1, 2v2)? Will it mater if you actually have proper pvp fit?
No, because you would have rats shooting somebody and pvp will simply not happen.

The point is that ESSes in anomalies do not promote actual pvp activity, and i would personally prefer to have greater payouts for the ratters and no anchoring in anomalies, so i could simply have the chance of blowing something up, instead of playing games of pod-luck that involve rats.

PS to inform our less experienced friends, ESSes which are not in anomalies (and thus for the defender "unsafe") usualy have a fraction of the money, because the defenders share more often, and also get defended more often.
