Someone claimed it's bad for site ranking with search engines if obvious garbage is up?

I'm not going to say you shouldn't report spam posts, but I will say that generally it's not difficult to see which threads are spam threads, so it's not a big deal if they aren't reported. We are grateful for all posts in other topics though, they are harder to find when e.g. looking through the new posts page.

FTR, I’m not going to go into every post and report it though.

I believe it's better to report those posts to the mod team via the three dots at the top right than pinging individual mods.

If we are going for historical accuracy, should other civs have empire phase (like Persians, Macedonians, Han, and others)
