However, Secret Servers do not have the hardware to install more than a v0.3 FileShare and the quantity of Secret Servers is limited to 20 per faction, or something like that.
there are 200 secret servers. all you need is to do some searching and you will find loads of untouched servers waiting for your fileshares
Some of us didn't bother to count because don't need Secret Servers after a couple days into a round.
