I get around 60 calls a day, many of them are repeat attempts. T-Mobile's app blocks 99% of them. I get around a dozen texts a day for the real estate nonsense. Messenger does a good job of marking those as spam.
I've tried a number of times to get identifiable information from those folks with little success. Friend of mine went through the process and met with someone on site at the property he was contacted about. He first had to let them send an inspector. The inspector was paid by a proxy which was not linked to the company that wanted to buy the property. The person he met with on site representing the property buyer was a lawyer, and that's who he had to go after. He ended up getting the $1500 after all of that effort, and told me the lawyer laughed and said the cost was just passed onto his client. It was a lot of effort.
