Question re HC Merit System:
Is it possible to post a negative favourite vote against a poster without TOUing them and therefore making that poster invisible?

I once TOU'd a CVI frequent flyer, with the effect that threads with his/her posts became incoherent with this person's posts extracted. So, I never TOU'd after that.

By way of example, when T4 was becoming a little nasty to some here, I would have been inclined to post a negative favourite upon him, but making him invisible would have been a mistake.

Have I got it wrong?
