Would it be an option to remove signatures on that board?
No, or you have to remove signatures everywhere. Besides, I remember seeing spammers without signatures, just spamming their blogs and websites.
The solution for this problem is easy, warning then temporarily ban, not sure if we can disable posting there for spammers.
Mod
jgarzik made only a few posts in the past years, and hasn't been online for more than a year.
It is a honorary title for jgarzik rather than a position. That is what I told by a mod or an admin in the past. I can't remember anymore.
The problem with the press sub is having duplicated topics with the bitcoin discussion section. People prefer to post there because most signatures campaign accept it rather than the press sub. At the end, we have few members posting and having few spammers there will look exaggerated.
I blame partially the staff for the current situation. I should say that I reported so many infractions in the past when I was more active and they dealt with it in few hours but what I was frustrated about is that they don't ban them when they repeat several times their intentional mistakes like coinidol.
I don't want to see the press sub closing because the quality of the dozen posts there is better than the hundreds spam I see in the bitcoin discussion topics.
Good luck for everyone trying to fix it.
