PBNs and Reseller Hosting

I currently have the basic reseller hosting plan on hostnine filled up (19 domains). I'm expanding my PBN and I'm wondering if it's safe to upgrade my reseller plan and have 40-50 domains on the same reseller hosting? They have different C class IPs, but I'm wondering if this is still a footprint or if I will be okay doing this.

Dont use same hosting. Use different hosting per every 2 to 3 sites. Using same hosting provider will leave huge footprints and make ur PBN useless.

Your best bet is to split the hosting providers, do not upgrade. Just go for a new one, play safe.
