Pros
You only have to work a minimum for 12 hours. You set your own schedule The word count is 75 characters, which means it's one of the only sites that has that low of a minimum. Most sites require 150 characters or more. When there are 100 plus messages in queue you can jump into do something called freestyling which is doing messages off the clock.
Cons
You have to do 1500 a month. (This shouldn't be too hard as long as you can make 375 messages a week. This is coming from someone who has been doing this for years and can average 35 to 50 messages on a good hour and about 20 on a bad hour. You might have to pick up more than 12 hours if you plan on meeting the requirements each month) They will email you multiple times a day. Sometimes it's a update. Sometimes it's them telling you that you can freestyle. This wouldn't normally be bad if it wasn't several emails in a row. You are getting paid 10 euros of message which equates to about 11 cents in USD. This is some of the highest pay I have seen. You will be making about $165 a month if you're working the minimum required hours and making them minimum messages. So the pay per hour isn't something that you can live off of. I would consider this a side job.
