When I would glance at the newest registered user list I would often see the username - caty_____x

This is what I found http://www.mathisfunforum.com/userlist. … =ASC&p=389

Hi 123ronnie321;

That is a popular username for some reason.

May be a candidate for mass delete.

But what if catyhopofex is a real person? Or catylopyhex?

And it has become extremely popular since March 2011.

Perhaps somebody is learning combinatorics with names!

And out of more than 118856 registered users, less than 4000 users have at least one post. Less than 4% !

Hi MathsIsFun,

Yes, maybe.

Can something be done to make registration more difficult, like sending a verification code to the email address and user requiring to enter that during registration?

Currently: you get sent a password in an email, so the "caty*" must be automatically reading that and responding. So annoying.

Hmmm, I thought it was the same password we enter.

How about sending a simple equation to solve (addition, multiplication etc.), in a captcha if possible?

Hi all;

How about this, another member just signed up. Guess what the username is, catyfopywex.

That has been like that since before I joined. That 96% could be spammers waiting and watching for the signal to launch a single, massive spam attack.

Okay, bear with me now. Imagine all 114,000 posting e-cigarettes, viagra, homes for sale, organ enhancements etc at the same time. It would surely crash us and would be a dilly trying to delete all those posts later. It would be sort of like a Spamaggedon.

Hi,

Yes, that's a possibility.

But many of those accounts are more than a year old.

Hi all,

I would like to give some ideas.

1 - While creating an account at gmail, Google asked me my cell phone no. and sent me a verification code through it.

If you allow only one username per phone no. then this may be stopped.

2 - Delete users that are inactive for a long time.

Deleting old inactive users is something I should examine.

Hi MIF,

Take care that the number of posts = 0 before deleting.

Also, many users use signatures for advertising, is it better to disable hyperlinks in the signature section?

I agree. Or at least have that a user needs 100 posts before he can use a link in his signature.

Update:

We have another! catywopmoex
