These two are some of the few interesting ones, because there is actually some content there.
The pinterest account looks like it really could be hers. Judging from the content, it's been at least a year or two since it was updated. Interesting because it has a lot of gay stuff (shipping related as well as just lgbt), and shows her being deeply insecure about her body image (lots of fitness related images), etc.
The MAL one is almost certainly not her. Unless she kept it secret for some reason that Initial D and Air Gear are her favorite anime. Also, that account was made this August, so it seems a lot more likely that somebody just took her name.
