This is obvious when you think about it. What might you do, operating on the server itself, for which you need a recycle bin? In fact, for some, like Terminal Servers, you might need then, but not on others like a web server. In the meantime, it turns out to be a potential liability there. Thanks to The Elder Geek, by way of the SBS Diva blog (read this one for better details), for pointing this out. Susan, the SBS Diva, recently had a server compromise, and it turns out that the attackers used her web server's recycle bin as a video repository. Why? Because it's hidden. Removing the recycle bin won't stop someone from compromising your server, but it will take away one place they can hide once they get in there, so you might discover the breach sooner. And if you don't delete it, at least cut it down in size from the default 10% of space, which is far too big for a server, and probably for most client desktop.
