Four Months ago and $100,000 in check returns later I pulled the check option off all my sites, the fact is surfers figured out that they can easily enter bogus check information and gain access.
The last thing someone who is defrauding you wants is his phone number to be on file.
The system I now have in place forces anyone who wants to signup with a check to call in this automated system.
Nothing is foolproof but I believe instead of seeing 80% returns ill see 5%.
Feel free to test it by going to

Feel free to call in and block your number then enter the code you get online, its all integrated etc.
