While on Noveria, after you obtain Lorik Qui'in's data forcefully make him testify to help the internal affairs agent. After this is done you will get +25 renegade points. Before you leave talk to him again, question him on matriarch benezia, then scroll to ask another question, a new set of options will pop up including one to testify against anoleis, press that one to get him to testify again you will get another +25 renegade points. This can be repeated until you get this acheivement.
Edit: As of March 31/2017 this has still not been patched! Feel free to rack up all the Renegade/Paragon points to your hearts content (Thanks to DarkWingSpartan for last reporting in)
