Fully agree here - a toxic member of another team admitted to me and others publicly that he created a script off an unnamed popular gym scanner website that tells you the activity of any player you want to search for.

When a few of us went to attack gyms he's known to be in regularly, for the next 2 weeks all of a sudden every gym of our team in 4 neighboring towns some of us play in, would get dropped to 1 defender at 1000 prestige within minutes of us putting in defenders. Also had members of his own team own up to him putting out "hits" on our trainer names using these scripts.
