I develop and design websites/social media pages/ads for small businesses and pick up overflow from a buddy of mine who has an SEO firm. I really didn’t worry much about copyright 15 years ago, but the advances in AI apparently make it very easy for large content producers and license holders to seek out infringement. I’ve received some boilerplate stuff or had past clients forward me those emails. No serious threat of litigation for minor infringements. Generally just delete and respond. Then there’s the issue of replacing the content so I’d rather play it safe now. On the plus side, there’s a legal loophole that can be exploited with free trial memberships and commercial licenses. That can help when the budget is thin. :)
