People! This is easy.

Step 1 - Don't open door. Yell at them through door, accuse them of being infected, accuse them of being potential home invasion criminals (they are covering their faces - RIGHT?). Use the paranoia that the news/medical field has created against them.

Step 2 - Call your friends, and PEACEFULLY, in a group, follow them through your neighborhood. After all - it is YOUR neighborhood. (waive away the hipocracy of step 2 coming right after step 1 - we are at war and the nice guys get buried first)

Another idea - get multiple people to call law enforcement claiming harassment. It doesn't matter whether or not what they are doing is legal - what matters is that if law enforcement receives enough calls they will have to approach and speak to them.

The goal is to make them want to leave YOUR NEIGHBORHOOD of their own volition.

Don't be afraid of getting snarky (Joe already sniffed my daughter - he says she's all good!)
