Max walking speed, with default cvars, is 260 u/s (using the scout or holding no weapons), and max velocity is usually 3500 u/s. Nobody is getting close to the max velocity by the way. I don't really care one way or the other, but this server purposefully had 100 aa when it started (or around the time it started at least) for the sole purpose of bhopping/strafing, they even have/had a plugin to see if people are limiting their fps if their perf rate is too high. So I don't think anybody is doing anything that the old server managers would find offensive, of course disregarding what happened last year when they changed it to 10 aa. But don't worry, I doubt they will keep 100 aa on the server for long.
