I meant to emphasise “ **both** gateway and node”, but just to be sure let me rephrase for future readers:

Any hack for a gateway on the TTN community network that only works for specific nodes, is harmful. (Same goes for, e.g, single-channel and dual-channel forwarders, even if those work fine with some non-standard nodes that only use a subset of the channels.)

Also, as covered above: hacks on either gateways and/or nodes on a private network might be harmful for all networks that use the same shared radio spectrum. Same goes for pushing the limits in a private installation, like [apparently affects, e.g., Sofia](https://www.thethingsnetwork.org/forum/t/what-happens-if-someone-does-not-follow-the-guidelines/15298/15).
