If any of your regular inbound connections are doing this to you, it is the same thing.
You will be blocking them.
If they are not the ones, no issue.
Perhaps you just do not want to tell them to stop doing it ?
I can’t tell anyone how to run their node, but they do require monitoring.
I am not afraid to tell users not to carry with them WAN type connections.
And when they do it anyhow, I disconnect them.
If they do it a number of times, I blacklist them. They have to tell me they will not do it again to be removed.
I have 3 repeaters that can not run for 3-4 hours at a time in the hot summer for no good reason…They likely take it, but it’s hard on them to get that hot.
Many simplex nodes likely would have the same issue, even at lower power levels.
To judge by the number of connections tells you nothing about the traffic on them. For I have at any given point 5-8 nodes connected on a single repeater and most of them are utility in nature. And if I connect my repeater nodes together to a hub, that’s 20 nodes or so, with minimal traffic.
There are few ways to gauge the traffic level for how long of a period ?
hence there is no good way to do this outside of the above…
You have to state your policy and follow through. Or code some acceptable remedy on your own.
But you will quickly find the exact thing you want is not going to be the same as others.
And everything you do has wider implications, often not considered.
