Hey,
I do occasionally, when i notice, remove “bad” nodes like these on the screenshot below. Does it make any sense or i just wasting my time?
Thanks.
I think as long as there is any movement on those nodes (the Up/Down colum with increasing Up and/or the Height column increasing) it’s a lot nicer to help those nodes to sync.
When stuck at the same Height for a longer time they may need to be restarted by their owner in which case those nodes will have to acquire new peers anyway so I guess you could delete them.
yeah i know it’s not my point 
do i really HAVE to do it, is it better to have them deleted or chia client has efficient enough garbage manager and i don’t really need to be bothered.

upd
could my node be harmed in any way because of them during their lifetime?
You can keep them as long as you don’t have any problems with sync.
