Trust is just a guideline,if you want to go after people you have all the right to go after people.
One thing I have to say though before you go full on spam busting is this...
Some people have learning disabilities or had a rough go in life and did not get a education that a lot of us take for granted.
Worked with a guy that I convinced to join a forum and his spelling was aweful and people thought he was not all their and he stopped posting. So he was robbed of learning from this forum and felt judged. Now think how many other people are in that same boat that could actually learn a ton from people if we where not so critical of one another.

This business with the accounts personally should only be addressed if its cut and dry and thats up to you how clear that may be.
Trust as I stated earlier is for you and people that think the same way as you.
