What's happening with Instagram?

I don't use instagram at all, except when I wish to find some design artists or contact small business to buy something. I recently opened this after months, and went to search the artist I was looking for, and it's all Soft Porn.

How has the situation degraded so much ? If it's recommending this to me, someone who doesn't use the platform at all, what does it recommend to tiny teeny kids who just came out and are starting their instagram profiles ?

Was this always so bad or has it gotten worse ?

My curiosity took over and I scrolled, and guys, they're not even hiding it. A guy tying up a girl on bed, multiple videos of couples kissing, showing almost nude videos of having sex, although not fully shown (faces hidden) and just pure soft porn.

I didn't know where to ask this info and since all of my friends don't use instagram, I'm here.
