<font size="5">Paypal's Illegal Activities</font>
Customer comments are eye-opening: bad customer experience, spam, fraud, etc.
Paypal will not hesitate to steal money from your account, as I personally experienced. They stole $500 from my bank account, which is a lot for me; but even a penny stolen is still illegal.
Paypal also will not hesitate to tell you to destroy valuable items, which is illegal.

Similar red flags as Paypal: bad customer service, spam, fraud, etc.
And again, stealing money from people's accounts. It doesn't matter if $8000 is nothing to Moneybookers, they still stole $8000 and the victim here is the customer - not Moneyboookers.

More often than not, users justify the illegal activities of Paypal and Moneybookers because "it hasn't happened to me, so it doesn't bother me", "a few bad cases are to be expected, nothing is perfect", "there's no other good alternatives for money transfer", and other illogical opinions and arguments.
Don't be imprudent. You have options. But I recommend the following:
1. Watch your bank account for missing money, but don't be paranoid
2. Listen to ex-customers, don't be indifferent or rash in judgment
3. Search for alternative ways, in case what you rely on fails you
4. The fool and his money are soon parted, as the old proverb goes
5. The avarice is the root of all evil, as another old proverb goes
