Ignoring blacklisted server:

When ever I open gmod and join a server (any server) for the first time,
‘Ignoring blacklisted server: V4n1ll4 | darkRP - SEANANNERS&PEWDIES FAV @ 138.68.156.164:27015’
shows up in my console. Why is this, and is it malicious?
Thanks

It’s a server that has been blacklisted from appearing in the server browser for exploiting a glitch that allowed them to show their server multiple times, therefore boosting their traffic, if I remember correctly.

There’s nothing malicious about it, it’s merely a notification in case you are looking for that specific server and wondering why it isn’t there.
