On many forums and websites (this one perhaps included, I'm not sure), when a user goes inactive for a period of time (six months, a year, whatever), their account is temporarily deactivated, and they simply have to verify through email if they wish to reactivate after a period of inactivity. I've noticed lots that people will manage to dig up topics that are anywhere from 8 months to 3 years old (where that was the age of the last post before theirs), and it will make it to the front page; nothing will be contributed to the topic except for"The download doesn't work" or"Can I use this [build/texture map/mod] in my YouTube video?" thus making this anecro-post.
My suggestion is simply to have an auto-lock feature that temporarily locks a thread when the last post was created six months ago; if the OP wishes to unlock their post, they simply have to open the topic and hit a button that says to unlock it, thus allowing it to be relevant again.
This idea would be wonderful in my opinion, as it would:
- Spare members frustration who get unnecessary notifications about topics that were all but dead
- Allow newer, more relevant topics to shine on the front page, instead of having tons of topics filled with old information, and then"Can I use this in my Let's Play?"
- Save mods from having to manually lock posts because people decided to necro-post; this would get rid of it all together, for the most part.
