Last time I saw someone complaining about scrapers, they were talking about 100gib/month. That's 300kbps. Less than $1/month in IP transit and ~$0 in compute. Personally I've never noticed bots show up on a resource graph. As long as you don't block them, they won't bother using more than a few IPs and they'll backoff when they're throttled
For some sites, things are a lot worse. See, for example, Jonathan Corbet's report[0].
