Hello,

Since launching my service, ive been attacked by the issue of multiple signups via the form. Ive blocked out using same emails and some email extensions like disposable emails. But i still need help. People are using the GMAIL dot trick to successfully create accounts.

I want to limit one account per IP. How can I do this? Is there a variable in PHP for the files to get the IP of the user accessing the page or something along those lines.

Ive searched every thread possible, please i would love an answer to this.

Thanks

Hi

Allowing someone to sign up on-line and allowing them to make calls immediately is a recipe for fraud. I would suggest that you manually verify each of your customers.

There is no silver bullet for fraud avoidance, and combating it usually means combining a number of measures.

Hello,

Thanks jroper. That is what I am actually doing at the moment. They create an account and i check it and add the free credit. I was thinking if it was possible to check IP and only allow one sign up per IP then that would minimize ALOT of fake signups. I got 780 sign ups in 3 days and only 2 customers. So alot of fraud and mostly ALL from china, its ridiculous.

If there is another tactic I can use, please let me know.

Thanks

Hi

Well you may look at the maxmind solution, which does geo-lookups, so it only allows access from the country you are doing your marketing in.

Nerdvittles http://nerdvittles.com/?tag=security gives you a bit of a start, but the article is aimed at stopping phone calls, but you should be able to modify this to suit your application


With that many signups, is it a bot that is doing this?

No i dont think its a bot. They are all customers, sometimes a random idiot comes along and creates 10 accounts thinking he can get the free credit. I delete them all.

I dont want to do maxmind because I want my service to available from all over the world. Thats why IP was my #1 choice. Is there no way to do that?
