which Spam mod(s) for 2.1.4

[Nodaz]

Upgraded from an OLD version of SMF on a stagnant forum and it is current and running well, looking at mods now.

On the old forum i had several anti-spam mods installed :
Stop Forum Spam
and
httpBL
I wonder if they are considered good bad indifferent , can/should they both be installed, any other insight recommendations?


Currently i have these anti spam aspects active in the forum.

Visual verification image (set to Medium)  .

V2 ReCaptcha

3 verification questions( those questions follow for critique )

  (what letter comes after (e) in the alphabet (Cap sensitive))
  (What is the sixth letter in this sentence?)
  (add the numers, f i v e and 9, what is total?)

... any other insight recommendations?

The Image for Anti-Spam Verification Questions mod with relevant questions is very effective.

The built in anti spam options, The Captcha and Verification Questions are very effective imo. If you want some extra anti spam options by way of third mods, the one posted above is a very good mod. Additionally have a look at this other mod as well:

I took a look at The Image for Anti-Spam Verification Questions mod and quitw honestly i dont understand what it is or how it works.
This is the extent of the description

"Custom Image for use with Anti-Spam Verification Questions

Following on from a tip shared by Sir Osis of Liver this mod has been created to enable Admins to use a custom image for the anti-spam verification questions that are created via Administration Center >> Security and Moderation >> Anti-Spam.  The custom image will be displayed everywhere verification is required (eg, registration, guest searches, guest posting, guest reporting posts, etc).

Suggestion: Save the verification image to the forum default theme images folder (eg, ./Themes/default/images).

This mod also includes some safeguards just in case the verification image cannot be accessed via the supplied URL and/or if the verification image cannot be seen on the pages on which it is displayed:
1.  A message will be displayed in the Admin Center if the verification image URL is not valid; and
2.  On the pages on which the verification image is displayed a link to contact the webmaster is provided if the verification image cannot be seen.

Also, and even though the verification image size is displayed at a maximum pixel resolution of 300x300 on the registration page, the full-sized version of the image will be displayed in a new window/tab by clicking on it.

What image am i supposed to save, and if is display what is its function?
