I've been blocked by people on other websites despite not even once knowing who they were beforehand or even remotely interacting with them. Don't let it get to your head, especially with the usual clientele on a place like Furaffinity. A ton of people here are paranoid and unhinged lol.

Honestly I wouldn't let it get to you. I've never have been blocked but I have dealt with some nasty furs before. People need to learn to be respectful about those who make comments on their shit mainly because if you want people to like your shit than maybe try not to be a total ass hole and be what is known as cordial. People are always gonna pester about certain things especially if it's something that they like. If this is the case maybe I don't know focus on what they like and go and finish it. I don't like artist who just stop in the middle of a comic because of personal interest in the comic. I can understand life tends to get in the way sometimes and their attention get diverted. However if people are asking you for update maybe give them what they want. Because that more eyes on your work and more possible commission work that you can potentially earn.
I am a writer and recently have I started taking on story request of other furs to write out their story ideas for them to enjoy. Now eventually I would like to do a commission base so I can make writing my career but time and effort is key.
Anywho sorry for the drawn out opinion. I saw your post and felt bad because you were blocked because you were kept asking questions pertaining to the said comic. That isn't fair and down right wrong in my opinion. Like the only reason I would be willing to block someone is if they become hostile towards me. I have zero tolerance for bullshit. So yeah........ If ya want give me a shout if you ever need advise or want someone to talk to I'll always reply
