The proof is you and these accounts:
1. have the exact same style of writing
2. always comment in the same threads (of the projects you were paid to bump)
3. have the same local time in your profile.
You use a VPN with an IP address located in the Icelandic time zone to run all these accounts -- its a dead giveaway they are all owned by the same person.
Your comments are so devoid of intellect and substance its a wonder that anybody hires you.
You're the one without intelligence. The style of writing is absolutely different. The most likely time that the forum offers when registering and it just didn't feel the need to change. You, too, write almost always in the same themes, you paid for it?
