Do you have to "intent to hammer"?

[Raskolnikov]

I've played a game on a different account in 2014 and in that game people said "intent to hammer" when they intended to hammer (duh). However, the games I have seen that happened this year had instances where people hammered without stating that they were going to beforehand. Has the site meta just shifted to do this less or is it simply fate that I did not see any threads where people weren't completely sure that a player was scum?

Just to be clear, you're talking after they already claimed right?
