I've seen this exact same concept done the exact same way done on this site multiple times, and after 5 minutes of research I also found it in at least 5 variations on TF2stats and 4 variations on the steam workshop. And I guarantee that there are far more of these that I don't know about.
Okay, but seriously, I'm gonna tell you what I tell everyone else who does this sorta thing- leave it on the steam workshop, because that's fairly inconsequential. But TF2maps is meant for people who want to learn about mapping and critically analyze the design of maps. Sure we'll have some fun with some meme maps every now and again, but most of us look at this kinda thing with feelings that range from disappointment to complete contempt. Just keep that in mind moving forward.
