This doesn't really tell me anything Searinox. All I can do is guess what happened here.
To me it looks like You reconnected and the ghost Searinox caused mIRC to switch to your anick "Searinox".
By this output, it appears that "Searinox" is not a registered nickname and the ghost "Searinox" pinged before you actually connected with "Searinox_".
This script will not react unless the server notifies you of a nickname on notify list that is protected by this script.
Please provide me some more detailed information and I will be happy to help you :)
