I've encountered a player, who:
1) population does not grow
2) always gets rid of all the resources in time before my raid, ~ 4 resources of each are left in stock
I raided him like 5 times, every time I was able to gather little resources. And he always stuck on 140 population. I suspect he is someone's botted farm. I'd like you, the administration of travian, banned all his associated accounts.
