Hana explained that her profile, on which her bio reads: "who let you in here???", is open to both men and women, but it was only men who contacted her to share their concerns about her toilet roll positioning.
They pointed out that it should be facing the other way, so that the paper feeds over the top of the roll - not from beneath.
The Twitter post then attracted hundreds of comments, including some from people supporting Hana for taking a stand about the way she liked to hang her roll.
But many others insisted she was scientifically incorrect, sharing various versions of a paper roll holder from H.S Lane that was patented in 1888.
It shows the toilet roll with the paper falling over the top of the roll, rather than underneath touching the wall like Hana's.
"As can be seen from original patent, this is 'settled science'," said one person.
Another simply said of Hana's picture: "So very wrong."
"Those men are absolutely right. #Toiletpaper should serve TOWARD the user," agreed one woman.
But others were firmly on Hana's side: "They're all wrong, as well. Solidarity to you."
"You have it going the right way. I don't care what anyone says, the other way is seriously annoying," added another.
One even joked: "If you are trying to attract men, I would say your profile is working."
