Is this really about necro'd threads, or are you upset about the thread being about porn? Cause I still just don't see this as a big problem here. I am not trolling, I'm being serious. Or maybe you are right and there is a problem with necro'd threads and I haven't noticed b/c there isn't a system?

I'm annoyed because people are shitting in the forum and making it a PITA to use. We only have one subforum that gets any real use because the site operators don't really care about how the site is used. On a site where you have a couple of subfora to use things like this aren't really that big of a deal, but it's incredibly hard to get a post up here long enough to be seen during parts of the day.

Having bullshit posts of no value to anybody just makes things worse for everybody else.

Yes. They need to find a way to keep me occupied, and fast.

On topic:

Yes, I am also annoyed some times when my thread or a thread that should get more attention is burried because of bullshit threads/necroing

BUT

It's an internet community for gamers. Gamers love entertainment. For a community about entertainment to thrive you need your garbage to float sometimes. Remember, this is mostly about fun and games. We're not here to talk politics. Well... some are.

I like the odd necro. I would have thought you would too. It's nice to be reminded of friends that have left, and to see the community as it was a few years ago.

I really don't see it as a problem.

This is your main problem, not the age of the thread.
When asked about necroposting, I do refer to the threads as conversations in a bar. You hang with your friends, talk about relationships, movies, games and other stuff. If someone wishes to revive a topic you talked about in the start of the evening with "Yeah, that car is really nice", you would laugh at him, but if his comment was "You know, the problem with your car's engine may be in the gas filter" you would gladly return to the topic.

So it's not the threads, it's the posters. Locking the threads wouldn't help, we would just have more threads about the same thing, and you wouldn't be able to find the information you recall seeing in one of them.

A "The last post in this thread was over a month ago, are you sure you wish to revive the discussion?" could work, assuming people would read it.

Side note, and while I agree with you, on this hedwards makes good sense when this happens:
Someone answers a question you asked two years ago. XD

Or when something like this happens:

After decades on the internet, I still do NOT understand the problem that people have with "necroing" old threads instead of starting one with the, vaguely rephrased, same title and OP. I just "learnt" that people can't stand it. Yet again, I also learnt that people are dumb.

And now, locking old threads just to MAKE SURE ? Yeah, if it helps you sleep at night why not. Whatever.

I might agree on the general forums, but then again, you always find exceptions like bundle threads where a new key gets released a year later.

In the game forums, there are probably plenty of times it would be more appropriate to add to a similar question rather than starting a new one.

I doubt that limiting the ability to post in a certain subset of threads (such as very old ones) will do much of anything to reduce the number of threads going at any given time, or the percentage of "useless" threads. Inanity will find its outlets, regardless.

Edit: That being said, if a thread gets revived for obviously pointless reasons, e.g. by some newbie who's answering a question that was already answered long ago in that same thread, ruthless locking by a moderator is probably advisable before the thread goes meta (or off the rails altogether).

Hey, better late than never! :P

But if a necroed thread gets so much attention for it to get derailed it means it is popular enough for people to use it to have a little bit of fun. Otherwise it would just die on its own, eath to earth, ashes to ashes, dust to dust.
Calling for "ruthless locking" is just... fascism. :P

Yeah but sometimes I have no memory of asking it and I begin to think senility is setting in. Just the other day I got a reply in a game specific forum from something I posted so long ago I didn't even remember I had the game. Seriously, I had to go into my library and check. :P
