I have thried that and it didn't work
I am Free-lancer or virtual Assistant winning bids on free-lance sites to help with website deployment, plugin installations.
I do not own licenses (and frequently I am not aware beforehand that I have jobs to deal with nulled installations) so I cannot post in vBilletin.org, vBulletin.com or XenForo.com sites
Recently I had won a bid to install and configure KeyCAPTCHA plugin on a site powered by XenForo.
This KeyCAPTCHA not only failed to protect from spambot registrations but its installation made the already working forum inoperable and
I had to reinstall XenForo!
After my misfortunates I had to make some investigation
I pity I had not done it before!!!
I know when I was running phpbb2, there was a antibot mod that worked extremely well, basically just a few randomized questions. If that worked wonders, I would think something as "complex" as a puzzle should as well.
Jigsaw puzzles had been solved (assembled) programmatically long before invention of CAPTCHA
"If that worked wonders" then spambots had never visited your website
People have been far and few to start with <img src="images/smilies/frown.gif" border="0" alt="" title="Frown" smilieid="80" class="inlineimg">
People are simply repelled by advertising banner-CAPTCHAs
There are reports that KeyCAPTCHA decreases users involvement 20 times
- Google by string:
"BTW, just checked another phpBB forum where we introduced keycaptcha a couple of months ago.
Spam posts=0
Registrations down by 95% - not one complaint, but I can't deny it's entirely possible (if a tad unlikely) that many genuine members tried and failed to register - no emails"
increasing spam:
- Google by string:
"but spam on our forum and increased tenfold since installing KeyCAPTCHA. If anything, it seems less secure than the reCAPTCHA or the Q&A methods"
Note that the owner/webmaster of a "protected" webresource doesn't control or even see what is loaded from KeyCAPTCHA servers
directly to browsers of visitors of "protected" sites while KeyCAPTCHA "nusinessmen" do not even hide that they are professional spammers:
- Google by string:
"New Trends in Spamming: Spam Fused into Antispam Protection with Spamming Visitors Instead of Web Sites"
There are even more funny posts....
The KeyCAPTCHA Team's post I enclosed below [1] ells that:
- KeyCAPTCHA plugin had a bug and KeyCAPTCHA did not protect from spam
(more than a year)
- so, it just worked as advertising banner
- the corrected KeyCAPTCHA plugin is still not published officially
(on official keycaptcha.com website or on official xenforo.com website with this plugin)
while there were hundreds of posts claiming that KeyCAPTCHA is 100% unbreakable by spam bots
[1]
Again, I cannot insert link, google by this text that I copy-paste here:
- "Good (partof the) day,
herewith we enclose the attachment with corrected version of the KeyCAPTCHA plugin for XenForo, which is not published on our official (keycaptcha.com) web site, but it is fully debugged and working.
JS code of KeyCAPTCHA can be taken from the instructions for vBulletin, no need to change anything.
PS:
the version that was published by the topic-starter(TS) was not working and did not protect against spam, Even if the captcha showed up, the validation of visitor's CAPTCHA solving did not ever occur due to errors in the code of the plugin.
Sincerely,
KeyCAPTCHA Team"
