@Marvin Input appreciated. But yes I wished particularly for something that did not require prior configurations atleast from the user's end as a child can possibly reset them. Or logout if an account signin is required. I am trying to look into now to see possible flexibility.
So far swisscows comes quite close as they also filter the gross vices by default. They however do have a music offer which may not be ideal if not spiritual. Or you got to review it @narrowpath? While a lesser deciding factor, I find them less proffessed about their Christian position. For example when a coarse keyword is queried, their blocking explanation is essentially that they seek to accomodate minors as well and therefore cannot honor the query (would they otherwise honor if it were not that?).
Purebrowser on the other seems to be upto no good as they have a link (under the search button) to their 'own' news site which seemingly only contain posts from Christianpost.com and have a field where they offer subscriptions to the same news site (possible scheme to harvest emails perhaps?).
I have just learned that Google offers what they call 'programmable' search (paid and free plans). I wonder if that is what SI imtergrated? Google states that they let you choose what sites to include etc. This would be great especially if one can also enable their SafeSeach by default. I hope to look into this as well.
P.S: The said Pure Browser's news site seems to
only contain excerpts of the news posts and not the entire posts. Which makes material difference. But it is still odd that subscriptions to their news site is offered thus. I purpose to look further there into and accordingly upadate this post.
