I haven’t found a setting for this, so I’m assuming it doesn’t exist (pardon me, if my assumption is incorrect). Sitepoint is in the process of removing 1700 blocks on IPs because a good majority of them haven’t had a recent match and a few of these are blocking users who seem legit (as they email our support team asking why they can’t register/login). So I’d like to see a setting that would auto-purge blocked entries if they fail to have a match in the last n months. Mockup: ![](https://global.discourse-cdn.com/meta/original/3X/2/7/2756240a497ef9059dde99eacd60e116f4335043.png) Default would be 6 months (or longer) – I feel that may be a safe default. ---

From past experience I’d say most problem IPs\* fall out of use within 3 months, a large several persist for around 6 months, and only an extremely rare few for a year or more. \* I’m talking sub-net blocks, not individual IPs 6 months sounds like a good compromise IMHO, not like they can’t be added again if they return. ---

Yes, it is likely longer than necessary, 2-3 months would be ideal from my standpoint, but I figured more people would be happier with 6 months. ---

This feature already exists. I believe @zogstrip worked on it? ---

What is the criteria, as we have 1700 IPs many do not have a match in the past 6 months, some don’t have a match as far as September of last year. Also, several do not have any matches (they have a 0 count) ---

> [@cpradio](#): > > Also, several do not have any matches (they have a 0 count) So as to prevent any confusion, those would likely be my doing. When we were working out how to do things I manually entered a few IPs for accounts that were 99999 Suspended But they would all be fairly old by now - early Autumn-ish - and should be OK to prune out. ---

I’m not certain on that, several were created in April of 2015 (29 to be exact). ---

Some yes, but not all of them. ---

Ah, I tried searching for delete, that’s why I never found it. I’ll look into it. ---

Okay, we set it to a shorter time frame, will look at the results over the next few days to see if it is operating as expected. Go ahead and close. I’ll open a bug if it isn’t working as expected. ---
