There are idea how to steal employee money at freelancer.com. I was its victim. I share it for employees to never user "hourly" billing.
So, when you create hourly project, you set price per hour and how much hours you permit to spend during a week. So, lets say, you have 4-hours project, you set $10 per hour, and you expect to spend $40 max.
However, freelancer.com hourly limits are BULL$#*!. These limits are not enforced. So, employee can manually add hours and you will be FORCED to pay them.
So, now employee adds 100 hours manually and your credit card is charged for $1000 now, even you set limit to $40 and never expected this fraud.
It is how it works. Freelancer.com encourages fraudulent guys to cheat the system by creating of limits (so you think you are protected) and making these limits not working (so fraudster can charge you as many money as he wants).

I added credit card to Payza and used it some times to send payments. One day I was unable to do that, because Payza wrote me error "transaction declined". I asked support, they sent me copy-pasted reponse that "credit card doesn't work, because CVV, billing address or expiry date is wrong. I wrote that everything is 10 times checked and correct and asked how could I use the card in past if CVV, billing address or expiry date is wrong. Support representative copied me the same message again. If you want to waste your time, Payza is for you. If you need to pay someone, Payza is useless.

I am middle-size company director and I hired near 100 freelancers on upwork.com to do my projects. One day when I had to review job & pay, I received message from upwork that I "send too much private messages", and that I am locked to send more ones. By theirs own rules, I have to use theirs private messages and not email or Skype to communicate with freelancers, and now they say that I use too much messages... are they crazy? I could not to contact people and pay them money, so near 100 freelancers didn't receive theirs money because of upwork crazy rules. The for sure don't need big clients who honestly hire freelancers and don't propose to speak via email and pay via PayPal. They prefer actually to force me to not use theirs expensive internal payment and theirs buggy messages and to work with freelancers directly.

Theirs so called "security team" terrorizes legal loyal users. I receive spam and fishing message regularly, and theirs "security team" can do nothing. However, they block your email some times per months without even explanation the reason. I loss incoming business mail regularly because of them, so I switched to gmail. Don't work with these incompetent guys.
