How to to avoid user to have more than one account ?

Hey,

How to stop users to register more than one time. I want to avoid one user have more than one account .

Is there any tech tips on it ?

Thanks

 

There is little you can do to enforce it.....

You can check IP numbers to see if an account is associated with the IP already however people using proxy's will all appear to be on the same IP and most have dynamic IPs so they change any way

You can place a cookie on their PC and refuse sign up based on the cookie but then someone could delete the cookie.

Ensure all email addresses/ details are unique but many have more than one email address and can easily fake other details


Your best bet really is to more simply accept people will have multiple accounts and more look for post registration duplication (eg in a forum someone replying to their own thread under a different sign on - both IPs are the same) but again you have the limitation on IPs etc

 

It is not for forum or other kind of websites. What if I am going to pay some amount new registered users ? I need to avoid re-registering the same users, to avoid them having multiple accounts.

I can not ask them credit card info, not everyone having credit card , and those who has will not be willing to share there card account info.

Can I check by PayPal account somehow ? as I know one user can have 3 accounts with PayPal.. so this method will not work..

But how moneybookers, google ( with adsense ) or other kinda of big websites checking it..

 

They cant either as I know people with multiple adsense accounts.

 

Pragmatically speaking, there's not much we, as webmasters, can do. Dynamic IPs and proxy servers have become so common that it has actually become too time consuming to hunt down such people.

 

Pay by check only.
The hassle of getting someone to let them borrow their name and cash a check for them in exchange for a cut is enough to dissuade all but the most hardcore dupers.

 

Hmm maybe that is why , many of affiliate programs, ads networks prefer to pay by check..

Too bad.. I wish there will be a technology which will work on finger print based as authorisation.. Just imagine there is a keyboard and you are pushing ur finger and it is ur password ..

 

There are desktop sets coming with a seperate fingerprint reader, but it's just to create a strong password with it

 

There are ways of ensuring identity however they require installation of software.

The very idea of the internet is a massive security threat to both your computer and potentially you as an individual, as such browsers only allow limited access to information etc to mitigate the risk

 

I am thinking about the ultimate one person per account system. It will require that the user has a fingerprint recorder, which the system will detect any matches.

However, it will be kind of expensive, since you must supply the users the devices.

Peace,

 

there is one way to avoid that...and that is : the user must have a credit card to register to forum...so you can check his name...

 

Foreign cards you cannot check names, or uk cards even if you are in the uk, many people have more than one card plus to start accepting cards is one thing but to store card numbers and you get into a whole host of regulations you must obey regarding testing etc with the increase data security laws

 

I think that usually has to do with taxes. When someone cashes a check, there's a paper trail the affiliate can point to when the tax man cometh.

 

I have three different cards, all having different spellings/address.

The same is true for check. I can write it in my name or business name.

Peace,
