If you do things on the server that causes other users to complain, then you are not playing nice with others.
If you get slashdotted or dugg, etc. or otherwise get so much traffic that it causes other users to complain, then you are too famous.
Other users will complain if their sites seem broken or too slow, or if the server load is too high and the server seems sluggish.
They need more support help.
