yes but say all parent threads or children replies are created by user #213 Larry Johnson.. and you now delete Larry Johnson all posts with his usernumber anywhere remotely connected will stop functioning and will become broken. Also the way the user database works you will never recover the #213 for anyone else. Now while you could do a mysql query and update all posts with user #213 to a say a dummy with the name of Delete Moi who is say user #9037 and then delete the User #213 user I wouldn't chance it.
