Help

So I was messing around with ApocolapsyBot basiclly its a minecraft spambot. So I joined a server with like 100 alts until it got full. And then they start saying that they were going to report it to the police. I was not using a VPN so they know my IP. So my quistion is this actully illegal and can I get caught for doing this?

No this is not illegal (as far as I know).

They are saying that there server host has reported it to the police now? Should I be worried?
