I'm grateful that Kitbon and Sue did what none of us enjoys -- but if none of us does it, this site will become useless. Because of them, I don't have to answer to know something about the caller. Now, if inclined, I can call back from a public phone where I'll be tomorrow, and seek more details on the company. Tempted to gull them into sending a back brace to a police station, using the SSN of a dead person, but that would be stooping to their level.
Blocking works fine, and I use it when I know who I'm blocking. In the context of 800Notes, it might be a bit selfish. otherwise. It doesn't give the other visitors any information about who is calling, or why. It is especially useless in terms of diminishing the number of callers. Unidentified, they can go on forever. Nailed enough times, and authorities may notice. Some states actually have aggressive Attorneys General -- who can do nothing if nobody reports.
