It depends on a lot of things,
larger labels won't touch it, as I'm sure Ice Cube's label has a pack of lawyers that would tear you apart for not clearing the samples.
Smaller labels may risk it but don't expect your name to be on it, or you could just use a alias, then deny that it is really you
Most bootlegs are unknown remixers for legal reasons, especially if it's some corporate american superstar but if it goes down well and creates a buzz, people will find out who made it.
I have a few bootlegs in my collection, as it gives people who don't know any dnb songs a reason to dance when your playing to a non dnb audience
And with most of my bootlegs I could find out who did them, some said the remixer on rolldabeats or discogs under the catalogue number but others I had to do a bit of hunting for, and others I simply couldn't find
Eg.
Usher - Yeah (Mickey Finn Bootleg Dub)
Mariah Carey - It's Like That (Wickaman Remix)
Stevie Wonder - For Your Love (Greenfly Remix)
But others I could find such as the Urban Legendz series with remixes of Obie Trice, Beyonce & Sean Paul tunes
Note the difference, both bootlegs but lot of difference in the information know about the two releases:
Lupe Fiasco - Kick Push (Heist Remix)
Nas - Oochie Wally (Unkown Remix)
