It's debatable whether what 90 % on the server type ingame qualifies as roleplay in a stricter sense.
Gladly - from a rper's perspective - most people do not even type and try. Therefore they hardly harm a consistent rp environment. They are like NPCs.
But killing off everything that is definitely not roleplay (like stupid names) would help by making these "no-rp quasi-NPCs" no immersion breaker at all.
I mean, let's be honest: If you have ANY expectation of roleplay quality (like: you are a good roleplayer and you know how immersion can feel), you can only be disappointed by Disco "rp".
