@all,

I had a look at the script and I have the following warning:

Your /etc/hosts will only have the localhost entry and whatever list is downloaded from who knows where.

Any *actual* *useful* content you already may have in your /etc/hosts, i.e. the very purpose of this file, will be deleted.

If people REALLY want to *misuse* /etc/hosts for adblocking then I'd advise to make it very clear that any useful entries will not be there anymore.
