But in all seriousness, this is a valid suggestion. However, the problem resides in the ranking or skill level of the people. Furthermore, what exactly defines spawn camping/killing? If it's waiting outside and having the infected run to you, then anyone could be accused of spawn killing. Maybe adding an elevated platform or creating random spawn points throughout the map could help reduce, but the problem mostly resides in how people are stacked. Or maybe put an incentive to deter spawn campers by putting bounties on them, causing others on the server to look at them and target them. You could also possibly add a raised platform, that will not give fall damage if you fall or temporary invis where you can't attack nor be attacked.
