Out of what I can see there, only 50 posts in 2 days that got removed, of which a bunch were plain troll posts, stuff relating to Minecraft (probably a bunch of dumbass kids not recognizing they'd be better served in the multitude of Minecraft subs), stuff that doesn't fit into the sub (e.g. specific Tomcat/Payara/... questions), spam, "interaction/karma bait" (aka, "what's the current state of X") and completely generic/noob questions.
You'd have to look before this drama of course - since then the sub obviously flooded. I'm not familiar with Java, but it seems to me they remove quite a few reasonable posts. Including some that got traction of the community.
