I also am having this problem. Last night there were 200 attempts blocked by the same IP. Right now, there are 500+ and counting by IP 209.235.156.70
Please advise why this is continuing even though its set to block an IP for 2 days.
I have wordfence free installed and working. Just not sure when it’s supposed to block an IP for 2 days – how the same IP is blocked 279 times in a 15 minute window.
