I don't block that because it's just facebook getting image and text information from a thread or a post someone has posted to facebook. It's self defeating to block this, it's your friend. Same with twitterbot.

Well if thats the case and its actually in vbulletins standard WOL then it will either disappear after his online timeout setting in admincp or the Ahrefsbot is using a UA that doesn't have Ahrefs in it, if he is using Paul M's Who has visited or a similar mod then it will appear always as both mods are doing their job!, i've mentioned this a few times.

EDIT: this is actually mentioned in the FAQ thats referrenced in the mods description.

There user agent was comingup as this: choopa: choopa.net: I placed both of these in. They had at least 20 different ip addies.

You only need to enter choopa if that displays in their UA and they'll be banned immediately and will disappear from WOL after the WOL timeout, the ip's are of no consequence, i have a ban ip mod but this one ban's the string found in the UA so they can use 100 different ips for the same UA and still they will be banned :)

That's what I did yesterday morning, but in the afternoon I had around 36 ahrefsbots under the UA Choopa.net I added choopa in the morning to your mod but they where still there in the afternoon that's way I asked. I haven't seen them this morning though..

Do you use any mod for who visited statistics? if you dont the only other explanation is that they had already accessed a thread or area prior to you banning them, the only time they can be banned is when they release that thread or area to move to another, after that they're history :)

I have boofo's mod for displaying spiders. I'm not sure if any spiders can view our site you need to be registered to view any content on our site.

Great mod and thanks for your help..

It doesn't matter that they cannot view any content, your thread url's are being indexed which is why you are being crawled, naturally they see the same as guest, just viewed your site you should also turn off displaying WOL for guests, it will save you queries and bandwidth :)

Cheers Simon :D

The feckers are still getting in: AhrefsBot Spider 02:15 PM / Viewing Index NIRC: 173.199.115.83.choopa.net

If thats form the logging then yes you will get that until every thread they have tried to index previously becomes a 301 permanent redirect, if not, if you want to pm me temp admin access with all permissions i'll take a look and see what i can do for you.
