I’m so sorry you’ve been mocked, that’s really bullshit :( I know of a few people that it’s happened to, and some have decided to stop submitting while others keep submitting.
I wish tumblr offered a proper way to block assholes instead of the crap excuse for block they have now; as it stands blocking just means the tumblr owner doesn’t see further notes from blocked people, it doesn’t mean they can’t reblog and say nasty shit.
It’s just another example of the shit that fat people cop and I wish I could make deathfatties a safer place but unfortunately tumblr doesn’t provide the tools to do that.
I hope you’re ok. Whatever you decide with regard to submitting or not submitting further photos that is absolutely up to you. I wish I had the power to kick fat haters in the shins.
