Do the majority of Private Trackers log all IP's used on an account or just the most recent?

Hey guys, I always worry about logging into several of my trackers with my VPN on. For the simple reason for streaming purposes I'm constantly changing locations etc. I haven't ran into any issues yet. However I would like to prevent it. I understand Trackers do allow VPN's however it has come to my attention that some don't!


Anyway as a general rule of thumb do the majority of Trackers log all IP's used on the account? Or do they just keep note of the most recent? Or do some trackers even keep logs at all if VPN's are allowed?
