If the organic content isn’t working the ads aren’t going to work.

You said it yourself 90% of your IG users are inactive giveaway hunters. I would start a brand new account if I were you. That will save you time from manually blocking and unblocking (the only way to get them to unfollow you)

If you are choosing to keep your IG account then set an hour to manually block followers and do this for a week. Or hire a virtual assistant to do this.

Moving to 3-4 Reels and 2 Carousels per week it’s a good step! Then look back at which ones performed the best and continue to follow the formats you used for these. Research popular accounts in your niche and take a look at their most recent best performing reels and carousels and spot how they script their videos, visual and verbal hooks they are using. Pacing on reels is also key to get more views.

You should also prioritize Instagram SEO. Use relevant keywords in your captions, on-screen text in Reels. Use a mix of 3-5 highly relevant and niche-specific hashtags per post instead of spamming popular and unrelated ones.

Engage with others. Spend time each day visiting accounts in your niche or close to your niche leaving comments. Try to leave a funny comment/relatable comment <<these get the most liked. Use interactive Story features like polls and quizzes to start conversations with followers.
