X/Twitter offers zero swoop-in protection for a handle when you delete your account, meaning anyone can "swoop-in" and instantly claim your handle, even pretend to be you and there is nothing you can do to stop them. If you don't want this to happen to you, don't delete your account, just stop using it. Technically th imposter isn't doing anything against TOS as the handle was free to claim due to their lack of protection policies. #x #twitter #security #privacy
