Any bot interacting with (or 'spidering') any server that does not follow these rules should, in theory, be denied access to, or removed from, the affected website.
If the only rule implementation by a server is a posted text file with no associated program/software/app, then adhering to those rules is entirely voluntary – in reality there is no way to enforce those rules, or even to ensure that a bot's creator or implementer acknowledges, or even reads, the file contents. search engine spiders – while others can be used to launch malicious and harsh attacks, most notably, in political campaigns.

While the attention of bots is programmed to spread unverified information throughout the social media platform, it is a challenge that programmers face in the wake of a hostile political climate.
Binary functions are designated to the programs and using an Application Program interface embedded in the social media website executes the functions tasked.
Examples of providers include Recaptcha, and commercial companies such as Minteye, Solve Media, and Nu Captcha.
Captchas, however, are not foolproof in preventing bots as they can often be circumvented by computer character recognition, security holes, and even by outsourcing captcha solving to cheap laborers.
