constant connection to ftp

Hello,

I have 1 crap server with managed.com which i use for free hosting.

Recently, well a few weeks already i added an account.

I have noticed some strange things in /var/log/messages


every second someone tries to connect through ftp with the username logs@thedomainiadded

of course this does not succeed so the ip in question gets blocked by my apf&bfd and put in the deny hosts.

Altough, every time an ip gets blocked the same situation happends again from a different ip.

my deny hosts has abouit 300 ips listed from this situation...every second there is an attempt...and it gets blocked, and then it happends again under a different IP...

What do you suggest i can do?
