i'm starting to see a lot of new people just randomly show up and bring old threads back from the dead that are univalent
https://www.gog.com/forum/general/cant_download
because this thread was created November 14, 2018 and a new post 6 hours ago. back then it could have just beena server issue.

i also did notice a few other threads also being necroed

Someones found it by searching or wants to add to the topic are the usual reasons.

That's a reasonably fresh thread to be concerned about necromancy. If the new poster is adding something substantial to the discussion is this not better than starting yet ANOTHER thread for us to pour through?

Some folks actually use the search features on websites and post in already existing threads instead of making a new thread that discusses something that has already been discussed Ad nauseam. I don't see what the issue is.

Yes. This particular post is spammer post. You need a bit of skill to notice inconsistency between Ukrainian linking to blog hoster containing a lengthy post about 8 different Chrome-related fixes in English, while quoting GOG related issue without OP posting anything about his specific browser.

Based on previous responses in this thread, I say, this bot passed the Turing test.
