Hello, we have a client who receives donations online, however they are getting a few 1 cent donations from a credit card from China. We have discovered that this is probably part of a higher fraudulency scam and we need to have the ISP addresses blocked from being able to make these 1 cent donations every few days.
There are about 4 donations on the site, [url removed, login to view], and we need a programmer who can go into the database logs or .htaccess file to block this specific IP address from being able to use the donation forms.
Please provide your recommendation as well as your pricing to fix / update this. Thank you!
