That's not the precedent set by other similar, recent submissions though, - nobody complained about this other submission talking about an event in 2004 (also ~20 years ago): https://lemmy.world/post/32137161

If you want to police submitting to this community with an unwritten rule about editorializing titles to include chronological information:

• get the rule added to the sidebar instead of assuming people can somehow figure it out when there's no existing evidence of this precedent
• enforce it consistently

It's not my favorite thing to have a few people who don't even make submissions getting upset at me for following the diabolical process of (1) reading the rules, (2) looking at previous submissions, and (3) copying a title verbatim from a reasonable source. If there's something that people are expected to follow, make it a written rule or give me access to your secret mind-reading device. This community isn't called sysadmin_news so I'm not sure how I'm reasonably expected to know this.
