Okay I got it:
https://archived.moe/asp/thread/7709091/Gisele left basically no impression on /tjpw/ and the closest Anons came to suspecting her was pic related. She fooled everyone.
The only other comments about her were someone describing her as a "Literal Canadian Who" and that's it.
Also /tjpw/ during this period was agua central due to Natsumi's push.
