That's Blueyandmarshallfan, right? That account kept on persistently treating me like a service to find HQ images over the course of months. When I refused for the umpteenth time and got a response like "I'm not asking you for pics, I'm asking you for a place to FIND those pics, it's TOTALLY different" I decided enough was enough. They also sometimes did things I had to be apologetic for, like when I retweeted a professional hockey team auctioning off their jerseys that the players had worn with PAW designs, and Blueyandmarshallfan replied to my retweet with "Do they have adult sizes too?" when they were clearly adult jerseys, not getting how that sounded like an intentional insult to the players, implying they wore child-sized clothes.
Anyway, after I said I didn't want to be an image finding service for that user twice and them still persisting in asking me to be an image finding service, I had enough and blocked them.
Since then I've seen they went around Reddit, Fandom.com and Twitter on what seem to be sockpuppet accounts to try to turn people against me and stir up drama, and had someone else (?) reply with harassing tweets (which thankfully I didn't notice til much later because Twitter marked them all as spam lol) so bridges are burned and I find it highly doubtful they are indeed "very sorry."
I'm not a super patient person and I'm fine with being called a jerk for blocking people, but I don't want to be involved in drama and I don't want attention on anything other than nice pup pics that I choose to post in my own time, and the latest news. Like I said yesterday, blocking people also isn't that big a deal, since it's very easy to get around on Twitter - I just don't have to see that person's posts or interact with them any more.
I hope this is the last question I have to answer about blocking anyone and from now on it's just enjoying PAW together without entitlement.
