Anti-Block Mod.
This is how it works.
You start off invulnerable to all damage except your own.
If the mod detects you are not moving or barely moving then a counter starts, once the counter reaches the time (scr_antiblocktime) then you become vulnerable to ALL damage, so if you are being blocked by someone, give it a few seconds, and just shoot them [you will not recieve any score for killing, so do not be worried that killing will get you kicked]

If you are vulnerable because of blocking then the only way of becoming invulnerable again is moving.
The only drawback I can think of (without a proper test) is waiting to jump. If you are waiting to jump, make sure you do not exceed the counter. if you have an idea of how to solve that problem, say so.

Anti-Kill Mod
Simple. Only damage that you cause yourself can kill you. All other damage is ignored (unless you are blocking). Also, falling damage is off, unless it becomes a problem, it will stay off.
