Ain't know who is this Unknown01 so I'll not argue about his troll and I don't even understand the arguments in your local sections since it wasn't my language, the most I've been concerned about is why someone is proposing to remove this wonderful feature that possibly helps to combat the spammer or just spamming for the sake of a signature campaign. IMO, nothing special to him to be worried and listen to his troll, but instead putting him on our ignore list would be better.
I voted no, it should continue to be possible since it's very USEFUL to keep the forum clean and maintain healthy from irrelevant discussion. When you're a topic starter and open a discussion thread, this feature helped a lot and it's better than locking your thread to avoid spam.
Though this feature is nice and the same on a merit system or even in a DT system, it could be also abused by anyone else.
But at least can be traceable through the archive tools.
