Ms Tanya Ward:

The principal problem is that taking more proactive measures interferes with their business model, which is something they are just not interested in. As Mr. Church said, it means their profits would not be as high because they would need to plough them back into safety proofing and privacy proofing.

One of the other big problems is that they put all the emphasis and all the responsibility on parents, which is just not acceptable. Parents cannot be with their child at every point in the day when they are in the online world. They cannot be outside the front door either. The focus needs to be put back on them to make the Internet a safer place. For a long time, they have got away without any formal regulation. We know the harm that is being done. We know they are making enormous profits. The time is now right to start that journey to having regulation. We also need to get the balance right with the protection of human rights alongside that.
