I'm still seeing this issue and it is becoming more frequent -- now several leads at random companies are experiencing this, where it used to be several leads from only two companies.
Has anyone else seen this? I've re-configured our scoring to only let them run through "clicked email score" once per day, but some of these are spread out over a month.
It definitely can't be forwarding because the clicks are ridiculous -- DOZENS of clicks and spread out over time (i.e. AFTER the event is over they're still clicking). Our click program also EXCLUDES the unsubscribe link, so it is not that.
