Practically every site has at least one or more types of bots. Not all of them are nefarious. Some provide the site owner with valuable information about the number of hits, memberships, and referrals on or between a given time. Information is key but unfortunately, some sites delight in harvesting as much personal data as they possibly can. They often go for all types of information, much more than Name, address, numbers, sites visited, associations, relatives, history, financial, criminal, social, and many other types of personal data! Yes, everything is for sale and it's not going away any time soon so buckle up!
All the more reason to try taking some safeguards with one's personal/private information. Use long passwords or a password manager. Use a decent VPN and exercise caution with suspicious sites or ones you haven't visited prior.
It's just an ounce of prevention, that's all. If someone really wants you or your data, they can most likely get it. Remember, everything is for sale and can be bought!
