For now I'd say a new thread. I think it's easier for us to keep track of them that way. The other threads that become 20+ pages long end up being a bit hard to track.
I noticed that with the dupe thread, but that can easily be manageable by replying with something like "done these" or anything of the like and then just work with links from that point each time. In any case, some info on how page deletion works would be good. I know Giant Bomb has new thread for new deletions and then they are just locked when done (with a reply ofc). Maybe that perhaps?
This.
In case you didn't know, though - we *DO* already have a dedicated thread for reporting "Dupes" (multiple entries of the same item) only.
AND...
...Welcome to VGCollect
Well dupes isn't the same as reporting pages to be deleted
And thanks!
