The counter I would offer is that stalkers can stalk the wrong person by mistake.
It could be a family dispute (like child custody, for example) where perhaps private investigators have been hired.
Cbgb, this is possible, although the poster did not offer any reasons why s/he would be stalked by this largish group in this manner.
So perhaps a trusted friend or family member or two could stay with him/her for a week or two and help assess whether the threat is indeed serious or if paranoia in some form has set in.
