And here is the link to that plugin https://developers.oxwall.com/store/item/671

The only sure way to take control of this is to approve all new members yourself, at least for a whiie.   Many of them will hit a new site and then move on.  

There are other techniques and some work better than others, but forced approval will help stop this.  The other thing you can use is recaptcha or a question captcha on registration. 

I also use the Trashmail blocker plugin, but according to its logs, it's never been needed so far to block any trash mail. 

now i sue skadates recaptcha but i not sure that one is good

i do not know if daves recaptcha support many languages?

If you want stop fake accounts spammers then i suggest the fingerprint plugin in oxwall store, it will stop them for sign up for a new account. the plugin is in beta mode now and some bugs need too bee fixed

here is the link https://developers.oxwall.com/store/item/1344

However be carefull with watchdog, the table is huge and i mean really huge. If you ever have to restore your site and the watchdog table you will need to restore it in sections with multiple queries because its so huge. If you try it with one query it will more than likely fail. 
Also it takes up alot of resources as well.   

Maybe i will try your ultimate captcha plugin, then it is first time i buy a plugin from you :))

But i would like know if i have 1 of this 4 captcha in my skadate website already and maybe that captcha is okey to use...i think only skalfa can answer that.

My skadate captcha look like this screen shot..

I have one question more:

I have this watchdog plugin installed now and there is not history when it prevent someone from join you website only realtime you can see and who have time for look that everyday.

So my question is maybe little off topic what picture or page will they who this plugin prevent for join see when they are not able to sign up?

The default captcha style was beaten just after it was released in the industry, no its not that good, bots can get past it quite easily.  It is there as a "better than nothing" deal. 

My question then must bee why have not skadate or oxwall update this deafult captcha to better one for 2 years? or is to longer?

Anyways then i will go ahead and try use your plugin if it is supports many languages as you was told

thanks dave

This must be helpless as the website owner

I see that as a user Oxwall

Oxwall demonstrate their exploitation in a very simple issue

Can provide the solution by adding a very simple coding for such a system

dont no providing solutions that Oxwall

Now I see that provided a simple plug-in control Above all Oxwall

This control system can break, but this time could show instability

Not too late for that

Oxwall team needs to add an emergency must complete 2 missing

1 show user IP (Admin)

2 User IP warning (should you delete logged in 3 months following the entry into the system)

Oxwall base is maintained based on 2 peopleIf you click on the same page, which shows the results.Make sure people use Facebook to include ranking 3rdI-friend-a friend of a friend.Let me give an example of a group Group page is seen in all media queriesMy private group only got to look around me.Widgets last login feature in the foregroundemanation of real-known throughout the worldAll sites that are not scoring system shows the most recent entry-representation vote-rated.I think humor should make some changes in the residual OxwallCan not be limited as much a process with plug-ins.A lot of attention because it is in use Oxwall prfoyonel part of the country.non-professionals is very difficult to see in this case.not complex but difficult platform. Deficiencies should be remedied.

Also try the slide captcha, its also a great choice.  Not the old one but the new one that i use in my plugin. The old one was already beaten, and use a numeric value or use the reverse slide.  If all of those fail then it means that you have a bug or a exploit or something going on where they can bypass the captcha.

what captcha do you use dave? can you make them in order best protection 1-4
