Lazy? It's strategy. Figure out when they collect and then pop two terrace farms instead of just one.
To me, how he states he attacks/plunders everyone in his hood does seem a rather lazy method, or perhaps simply only able to log in once a day for limited time. Whatever way is fine, however he wants to play his game. But it shouldn't be particularly worrisome to a plunder target at all.
Stated strategy is that he goes thru attacking all his folks then checks right away to try to plunder something good. If nothing there of big interest to him, then he's not checking back to try to figure out when they collect. Instead, he waits until his plunder window is almost up, then plunders everyone who he didn't do at the very beginning. Since his next 24hour attack/plunder window starts again in a few minutes, he's able to reattack almost right away. Looks for good plunder immediately after, then repeats his process again - not checking back until time's almost up the next day, then taking whatever he can get at the very end.
He's an easy plunderer to counter. Change your collections to most any other time of day, & you'd be fine (even if you don't collect on time). He's on a fixed schedule & doesn't check for potential loot except before/after his scheduled attack time. Usually it's only the plunder targets who are on the fixed schedule, having predetermined collection times.
