I can confirm that the method of logging in on the launcher without purchasing the game worked for me about 2 weeks ago.
I did a lot of research on here and you honestly wont know 100% until you buy the game. In my case, I left the launcher running for 4 days, restarted it, and left it on for another day prior to buying a new copy since I had read that people using this method were fine until 4-5 days in and then they got banned again. If you get through all of this and make it through 3-4 raids without getting banned you are most likely in the clear.
I got first offense banned from using the texture swap files and have played legit since without reban taking no precautions before rebuying the game. BSG does things differently for every case it seems so take my experience with a grain of salt.
