It is a fundamental problem, you can find it in so many topics. HO can do whatever they want. No response to applications, not maintaining their profile, false information. If the location or the house is good, the HO will always get sitters. But even if it is not so perfect, maybe a full-time sitter will come to bridge the time to their next sit.
But if sitters misspell the HO’s name or one of his pets on the application, write a standard copy/paste application referencing their maybe perfect profile, don’t maintain their profile or have no to few reviews, they will be sorted out immediately.
And since we can’t or won’t ask every HO for their reasons, we personally sort those sits out.
For over 20 years, I have made my living with software. And I have learned in 20 years just saying “please don’t do that” doesn’t change anything. Only challenging barriers like annoying popups, checkboxes to acknowledge operations or “if you don’t do that, you can’t do that” helps.
And in most cases, it is easy to implement. For that topic here, the solution is easy. If a HO tried to set up a new date, show him his profile, ask if it’s up to date and let him active confirm that.
