I don't think it's still wise using it.
The script works, no problem with that. I still have a bunch of sites out there on free hosting accounts.
The problem is the outdated IP-list.
I just checked the login page where they give you the option to DL an updated list. Unfortunately it doesn't have a timestamp.
I wanted to check the forums but the URL redirects to the CloakerLive page. Wonder if the forum is dead. The last couple of times I was there, it already became clear that support for the script was dying out.
I compared the IP-list with the Fantomaster botbase and it's a different format. So no easy way to use that with SEC. Not without some coding experience I think.
Compared with all the options you have today I doubt it's worth investing in it again.
Even with EWI it took time to set the sites up.
I moved over to more automated solutions.
