Browse host isn't reliable at all. You might be unable to browse a host then 10 minutes later the same host can be browsed. You may see 30 files when browsing a host, 10 minutes later you can see 100 files from that same host.
You have more chance of being able to browse hosts who have chat enabled, but even then it's very random as to who can & can't be browsed.
Users who are firewalled are very hard to browse.

There's no option to enable/disable browsing.

sup y'all (note the gangster/redneck accent...)
I hate bumping... but I got a good technique....
I've done this various times.. (yet I never realized it..)

Put your cursor over the file...
A good file should read... (As follows)

~~ Example~~ [for educational purposes...]

A song - Vicarious
Title: A song
Artist: vicarious
Album: I kick-***
Genre: nu metal
Length: 4:00
Bitrate: 128
========

Something like that... I do this all the time.. I just now realized it works... most of the time....
Note: Look for the length

Many fake files don't have length... try it out...

sticky this airhead...

Erm...are you talking to me?

Some fakes don't have length showing within extended tooltips & some have the length that you'd expect. Some fakes have zero as track number. Some have TRACK1, sometimes you have a run of files with identical tooltips info - starting from the file with 100 sources down to the file with 5 sources. And sometimes the info looks just as you'd expect from a legit file. There's no one thing that stands out...people should stay away from anything that looks remotely strange.
