I made one mistake when I wrote my previous message, user actually had activity at the same time threads were made (16:21, not 18:21). I suspect these threads were made by activity from this user.

Also, today after I left mod running, I have more similar threads without name of user (so email confirmation process didn't worked through).

In one instance, there are two threads created one after another, and in other there are three threads created in array.

I'm not convinced it's the bots, there would be much more threads, I think that actual people probably try to confirm link, doing something wrong, not sure what as I always was able to confirm link without any problems when I registered test users.

This is really something hard to pinpoint, because sometimes mod works fine, no multiple threads, and sometimes there are multiple threads without users name.

Bots hardly ever successfully register on my site, if they do, I think that they are actual people, who manually do registration process and are able to bypass registration checks.

EDIT: I just noticed one more "empty" thread, but it looks paired with actual registration.

Time stamps of threads:

Empty: 19.12.2013, 8:28:35
With user name: 19.12.2013, 8:29:15

So, after 40 seconds, there's thread created with user name. I assume, user tried to confirm email, didn't succeeded and 40s after that was successful and thread was created with his name.

All these multiple threads are seconds apart, I really doubt that this is bot activity. Anyway, I added to my "arsenal" this mod: https://vborg.vbsupport.ru/showthread.php?t=294633 so I now have two of three mods that you suggested for bot stopping from registering on my site (don't use at the moment Hostname or Useragent Registration Ban).

EDIT2: I tried to find if there's last activity for certain users who still need to confirm email address that corresponds with multiple thread creation and I found for triple threads user that probably triggered creation of threads, for double I didn't find, but it could be for more than one reason, e.g. user maybe later successfully confirmed email address (more than a few seconds later, so it doesn't "link" created empty threads, and when I say empty, I mean threads without username), or it could be attempt from "older" user and I didn't manually checked enough users.

So at the moment I have only one multiple threads created that maybe is from bot's activity, but it's not certain. It also could be legitimate user doing something that triggered threads creation.
