Croplocking.... like if skpikers cannot send 3k crop to the inactives and feed for 3 hours his 500 troops (+500 average inactive's pop) after arrival of his troops, more than enought time to kill hundreds of troops. Even without crop feeding spiking is effective in small villages.
It just make a little difficoult to spike but you lose 30%-100% resources raided, simply forever..... not seems to me a big deal.
you dont deal with spikers but create another bigger risk...
Croploking and resources... Really good idea! top raiders and skilled players would be incouraged, for avengeance, to zero inactive's infrastructure in all server that in the farmlists give them 0 0 0 0, and not do more work finding/distinguishing what inacives are crop-resources-zeroed, They would just zero all infrastructure of all inactives..... obviusly far from their kingdom!. I would be dedicated one on it, in that scenario, simmer and crop-resourcelocking players dont deserve to have neither a village with full building developed and no fields. and i'm sure they would not call them sucky.
So at the end you just risk to trigger a global war on those who destroy more farther inactives near enemy, involving even more kingdoms meanwhile...
Many seems be against inactives, and people that raids here.... i dont understand why.
Would you like to live in the world of wellness where there are more equal opportunity, meritocracy, and big goals to achieve.
or live immediately after a the end of a war where there are few resources, a lucky few and many criminals?
i tryed to do some speculation about a server with no inactive villages in this current system or very low raids from inactives.... and i arrived to some conclusion of global slowness of server, anarchy, less players, more sim city gameplay. no Great barracks and stables running for most of off governors.....more defensive players than offensive, internal fights in the kingdom, more weaker kingdom, more spread between gold user and not gold user, weaker player's cannibalization, last but not least your lovely interactions player vs player maybe will decrease, and even if for miracle they increase the Quality of these interaction will be for sure lower. Skilled travian players will leave Travian kingdom. (Multiaccount, sitting abuse, maybe increase?). TG says Goodbye to some money from this Kingdom versions.
Yeah... i know.... maybe is a bit catastrophic.
Btw by that time i'll have left TK long since. I dont care too much about future of this game. I just like guess how a game can improve, and how small factors can change the gameplay.
Current servers probably are the lasts, we are playing the best way we could, and how we wanted. No more motivation to play others, improvements happens too much slowly for me.
So please, read my words as the troll's ones. dont be scared. Travian kingdoms will become the best browser game ever, even with spiking , one day 
(Oh.. I was going to forget... in that scenario players like Accord will still be able to have fun... this aspect is important too, i suppose...)
