Trust feature irregularities

I thought adding the trust feature was a great add for the site. Sure, you can look at number of reviews and dig into reviews to see if a person is a legit PL, but the trust count was a good quick indicator. In looking at my account settings, I saw a ‘manage trust’ settings or something like that. When I clicked, I was surprised to find I ‘trusted’ about two dozen users. I only recognized half of them as people I remembered trusting. I clicked through them and there were a dozen members with one or two reviews I supposedly trusted. That’s just not accurate. I removed the trusts, but how did they get there? I didn’t do it. I changed my password to be safe but this is weird. Anyone else?
