Even if they set the bar low like every 10 synths I think this is an acceptable measure to help combat botting. The inconvience that genuine, honest crafters have deal with is minimal at best.

I have a slight feeling most of the opposition is/will come from people who are guilty of turbo spam or botting themselves.

At least SE isn't auto logging players out once they reach a certain threshold or force players to use one of those cyrpto key thingies.

Even if this measure halts 1 bot, it's well worth the effort. I'm sick of seeing the same players day in day out hour after hour sitting there crafting/fishing doing nothing but cheating.
