company cutting and pastng mumsnet threads onto their facebook page

[thisisyesterday]

I "like" baby and children's mattresses online on Facebook.
They frequently post parents questions and ask for a response.
Just now they posted one that I recognised from here. I asked if they'd taken it from here and they said yes.

Do they have or even need permission to do that??? The op might not have wanted it on there

Oh and their reply suggests that this is something they do regularly
