If something is fetching data from your server, you should be able to find out what it is and who to contact about it.
Parsebot identifies itself in the User-Agent header when fetching data:
User-Agent: Parsebot/1.0 (+https://parseapi.com/bot; hello@parseapi.com)
That gives the person reading their server logs a name, a page explaining the bot, and an email address. They don't have to guess whether the requests belong to us.
The Parsebot page is there for that person as much as it is for anyone using the API.
