That's true but what do you make of bounty campaigns here that expose email addresses of bounty hunters on spreadsheet? Do we take that as negligence on the part of the managers or a conscious effort to cause problems for hunters as some of them may not be submitting a throw away addresses but their real and business email addresses.
It could be one of different reasons and the reason will not be the same. Some use it for dubious means and could be selling the details on the dark web, Some are just negligent and feel that's the way to do it cause everyone else is doing it.
Lol... Oh, mine! You must've ended up complicating OP's confusion with that first line of yours. Those high sounding words are likely going to be problematic for a noob to understand.
If they have gone through the basics, then it shouldn't be that confusing, or they could just Google search for the meanings.
