But mostily agree with you, but I would suggest adding the length of time and number and quality of posting as a possible criteria. JMHO
AZBOB agreed most of the trolls post once without any info at registering and comment "we just love XYZ Reality they sold us a great piece of property that has just increased in value so much" or "When we visit San Pedro we always stay at Hotel XYZ they are so nice and friendly and we get a great deal", but they have an IP address in San Pedro.
I don't think you guys are Trolls, to many years of posting and I feel like i know who you are .
We could control the Trolls by having them at least give an email address when registering. It would give them some consideration that someone might be able to track them if they misbehave.
