No limit on carbon rods on neighbours buildings

I hope it's ok to post this but I haven't seen this anywhere on the forum, even within some of the topics, so I thought it would be worth flagging. Even when rods stop paying out on tapping criminals you still get a carbon rod for tapping on neighbour's buildings. The first day of the event, I didn't realise this and stopped tapping, missing out on about 195 rods because of it (3 rods per neighbours town x approx 65 neighbours).

So tap away, there's NO limit on neighbours buildings.
