Ok, so if you have just the first alias and it's working and you then edit that alias to point to a different filename, that's when it stops working?
Try typing these and post the output here (make sure you're on the network you are testing this on):
//echo -a $exists(post.ini)
//echo -a $ini(post.ini,advert)
//echo -a $ini(post.ini,advert,$network)
As far as the comment on this being spam related, this lets you send a message to many channels at once and uses the word "advert". It does look like a script for posting unsolicited text to multiple channels (i.e. advertising/spamming). It can be used for other things, but the choice of wording in it makes it appear to be for spamming and not just a server message or something like that. You really shouldn't be surprised if someone thinks this is for spamming when you haven't said what it's for.
