You can make a difference between alpha and omega accounts if needed. Let alpha accounts only count for 1/10 or something. Or let alpha only count once they have been omega before. All my alpha accounts were omega before. And I dont think many people would spend 250B like me to plex them. 
These are rough ideas. Of course we need to make them sneaky Eve player proof.
161 wars. Not copying it here. Go in game to see it.
However, looking at the first 20 of them
Alliance of 257 people.
11, 15, 16, 12, 11, 56, 64, 100, 10, 61, 35 member corps
And 8 more under 10 members.
Soā¦ Theyāve declared war on someone larger than them. Theyāve declared war on 4 pretty decent sized corps who could be capable of mustering a significant fleet per player numbers.
And a decent number more that could dunk a lone PIRAT member.
And that was just the first 20 out of 161 wars.
So yeah, Flipping the wardec costs around might be a sensible thing to do, but itās sure not going to slow PIRAT down.
Edit: And more importantly since itās not going to slow them down, itās not going to impact on retention from wars.
War dec alliances often go for smaller corps, cause they re cheaper. If you show them large 00 alliances that are cheaper to war dec, they will ignore the smaller corps more easy. Unless itās a contract of course. Then at Least Marmites donāt care about size. Itās all about how you use itā¦ euhh no thatās a different story.
The CSM Summit minutes, in conjunction with the problem stats shown to CSM by CCP, specifically state its a small number of players causing inordinate amount of player attrition via wardecs.
Do you not agree, that certainly sounds like PIRAT, and others like it?
Mine is bigger. 
That doesnāt present any strong argument against making your corp/alliance size be the number used for calculating your wardec fees, rather than your targets.
As mentioned above I donāt think it would significantly impact the war dec corps ability to mass dec people, but it probably would impact the target choice in the way you mentionedā¦ which could be considered a good thing.
Why are you off on this side tangent, Iām not disagreeing that PIRAT are an example one could use to highlight the issue, Iām saying that flipping wardec costs around to being based on the attackers size wonāt have a significant impact to the number of wars they are capable of declaring at one time. It ācouldā have an impact on their target choice to some degree, but whenever they target a PvE corp you are still going to have the same retention issue you do now.
Also keep in mind, many small corps weāre at war with, are small inactive corps that were kicked out of 00 alliances. Maybe CCP should add an option for attackers to retract a war sooner?
What is the total character count this 240-257 member alliance has active declared wardecs on at this time, in those 161 wardecs?
Iām not playing 20 questions. Make your point.
Edit: Also the 257 member alliance was an alliance they had targeted, showing they do target people their size.
Im asking for data I cant get through dotlan or elsewhere at this time.
Evewho and killboard dont provide this data either.
Go get it yourself, or pay me for that level of data entry work. Itās non trivial and the number is also irrelevant.
How much?
3 hour minimum call, so $100 should cover it. Aka Iām also not doing it for pretend money (And Iām pretty sure actually paying me real money would violate some kind of EULA thingy, so no, Iām not entirely serious with this, but it should make the point)
Lol, no thanks.
Ill do it myself when I get home, and post the results here.
Wont take me 3hrs either.
Good for you?
Itās still an irrelevant number. We all know itās a decent number of people that PIRAT have wardecced. And we know from CCP that it has a significant impact on retention.
The exact number currently under wardec gives usā¦ absolutely no new information that impacts anything here.
" War Declarations
In the EVE Leadership meeting the CSM was presented with numbers resulting from research
into the state of war declarations in EVE and those numbers quite starkly showed how
asymmetric the situation is, and how war declarations allow a small number of players to
negatively affect a huge number of people, with low risk. These numbers may be discussed further by CCP at a later date."

Sounds exactly like PIRAT and others like them.
Its anything but irrelevant.
I suggest injecting reading literacy, training it to at least 1, and then going back and reading my post again.
Or are you degenerating to trolling anyone now.
what about droping corp while at war?
I simply posted a quote from the minutes which is relevant to this discussion.
Are you affiliated with PIRAT in any way shape or form?
No.
To spell it out in shorter words since you failed to comprehend even on rereading.
It doesnāt matter what the exact number is, it isnāt important.
Itās a decent size, and thatās all we need to know. So all your talk about counting the total number is silly.
