Bad call I would say on that.
What's to stop someone from Ignoring Mod's and blocking their view in this fashion?
If I recall correctly, you can't put mods on your ignore list even now.
Now if you let him hide his posts from individual people he has chosen to ignore, who have just given him power to censor forum material freely available to all users from another individual.
It sounds bad stated that way, but it isn't like he can sensor any old material from arbitrary folks. He only gets to censor his own words, when he first says them, and only from people who he's not able to see himself. So, unless you're Crothian, it is a very small chunk of content, in a very specific situation, from a small group of people.
Using Bullgrit again to make examples.
Bullgrit has me on Ignore.
1. I can read his threads he starts but can not reply to them.
2. I can read his replies to threads but can not quote them.
Would that be a possible option Morrus?
I think (1) is far more powerful than the censoring above. If I start a thread, you can see it, but not participate at all? That's not just controlling whether you can see a few paragraphs to text now and then, that's controlling who gets to speak where. We have never supported that sort of thread ownership in the past, and are unlikely to start doing so now.
(2) only means the "quote" button wouldn't work. But if you just post a reply, use quote tags, and copy-paste, you get the same effect. I'm not sure that weak protection would be worth the code needed to implement it.
