That's a good reason why it's never a good idea to pay for DDOS threats - in many other popular extortion scenarios such as kidnapping, blackmail w. secret info or mafia 'protection money' for storefronts, the deal generally doesn't allow other, new attackers to make the same demands, so you actually are getting some protection - but here it does simply mark you as vulnerable.
Same goes when bribing a cop here. If you bribe too much you're targeted as easy money among the other cops here. Say for example you're caught driving without your insurance, you bribe and then every other cop knows you don't have insurance and squeeze you for money left and right.
