Have any of you encountered a Scammer or a real fishy person?

I am fairly new to Rover, I've only been sitting for 2 months now and I'd like to think I should trust my gut on potential clients. I recently had this person rise a couple of red flags for me. They were odd in the things they thought important to tell me and basically told me nothing about the dog. At first, I said yes to the request because at a quick glance (trying to keep my response time quick) they had a totally normal looking profile. I assumed the age of the person based on the name they chose for their profile - a name a Senior person would have. So I gave them some credit that the dog's bio said "he's really cute" and the 1 pic of the dog didn't match the breed. But just like my Grandma, she may think any dog smaller than 10 lbs is a Chihuahua. This person started to creep me out real quick after a couple of exchanges of messages and I quickly responded with a simple answer of "Sorry, something came up and I cannot commit to these dates." So far I haven't received any more messages from this person but it's only been a couple of hours.

Have any of you encountered a really suspicious person? I have reported the messages to Rover but how will I know when something has been done or if anything has come out of the situation? Are there more steps I can take to distance myself from this person? I have archived the request under "Owner was not a good fit", is there a block button?

If anyone is interested in knowing more about this person to keep yourself safe I can give more information.
