Many residential and business ISP's are the same dsl/coax/fiber company. Many of them will provide extra IP's for some tiny fee, so primary clearnet use can remain unaffected. Or you can route tor over vpn. Some do run exits at home. In that case consider contact local LEAs enquiring if they exonorator / informing them your project. Find your cyber / crime defense attorney to inform. And at least consider posting tor-exit-notice on your doors and clearly segregating your project / personal spaces and activities, encrypt / index what datasets you have, offsite backups. Exit issues have become very rare as LEAs have become educated over the years. Preparation is still better. After that, being a punk is half the fun and point.
