After making the fresh sync due to #42 I keep getting the error spam below on every restart.

Edit: Looks like it's coming from [INFO] - ban_address: Network is banning address 51.255.x.x, for 24 hours. since it gets banned and then the spam stops.

Is this still an issue, or was it just spam from a bad IP? If the latter, that could probably be worded better and be made to not log as an error.

I've tried to find it in the debug.log using cat debug.log | grep "check_proof_of_stake" but there were no results. I guess you're correct and it was only spam from a bad IP.

Closing then.

Actually, I'll re-open as a reminder to change the error wording...

I've received some more a few minutes ago after syncing finished.

I assume it will end once your new sync bans the spamming IP's.
