TBH the anonymity is most probably caused by the intensely toxic culture on Tumblr towards people who ask potentially "stupid" and rude questions. I'd like to specify I am not the anon, nor do I know them. Just throwing my two cents in on the matter of anonymity. Might also be they're just trying to rattle you.
Yes, I am very aware of the way people “converse and debate” here and I’m not fond of it at all. Lashing out, attacking and insulting each other doesn’t really help much. And I’m not gonna pretend I wasn’t prone to lashing out myself a couple years back. Now I’d just like to avoid it, because I feel it doesn’t solve anything. So if anyone wants to question my actions, then go ahead but let’s do it calmly and in a civil way alright?
