Finding a server to hack

Over the past 2 days i been hacking on many servers and i have notices one thing. Finding a server to hack on is extremely hard.
There are many ways i mean its hard to... Like, some servers just instant kick you because of bad scripts found, other servers kick you whenever you try to spawn anything.
Is there any ways not to get kicked or banned whenever trying to spawn something, or to avoid "script scans".

You can bypass script scans but won't be able to execute any script because you'll just get kicked / white screen.
Unless you have custom everything, then you can bypass ^.^
