To be fair, the best way to make yourself unplayable is to let anyone open a channel to you and be a big node. You end up with a few thousand channels, all of which are saturated, and only senders with a ton of volume who can try each channel open open a direct channel can pay you. 

 I get that, but the extra context here is that they also require KYC for customers buying a €10 pizza - at least in The Netherlands. So now they presumably want my node id too (not happening, I'll find a downstream node to open a channel to).
