if you'll have more connections or mentions on other IPs or websites, that'll grow the chances of them scanning your IP too.
You should read about how their crawler decide what to crawl and when*. After all, there's 4 Billion IPv4 addresses, and much more IPv6 (tho I don't know how much of them are used), and they don't just randomly spin up numbers to scan.
- I once read an article explaining how they did this, can't find it now. I'll send it if I do find it.
