Don't get angry, it wont help you.
RL Tibia is more or less gone already.. there's like 5 000 players left in there, (PLAYERS, not programs).
If a terrorist steal your pet and ask 5 million for it, if you pay him... a lot more terrorist will come to try the same thing.
Now when I've put this part in your head, change the terrorist to a DDoser, and the pet to the server internet connection.
I know lots of people who Dos "noob servers" for free items... not saying that's what happens here, but you should never give in for what someone else are doing.
If you've ever had any experience from managing a community you'd know this.
