If you import the ones that are duplicate, then simple, you will not be able to connect to all of them. You'll just conenct to one of thr duplicate servers.
You will not have any problems while loading any of these lists.
The servers I had posted in this thread:
https://forum.winmxworld.com/index.php?topic=3947.0.htmlare listed individually. so that you can clearly see the servers there as well as choose only the ones you want.
All the wsx files there have one server each. It might be a bit tedious to add them individually, but I am quite sure that all the servers were working when I made those posts
Download his (tinty's) servers and imort them as normal.
Cheers
