I don't know who will see this but I was recently a victim in an ao3 scam. Someone on tumblr was asking for an ao3 invite in February. I personally hadn't seen any scams that followed this format and I foolishly thought it was a legitimate person just wanting to be on ao3. I had one invite I had never used and thought I would be nice.
A month later, I get a message from the same person harassing me for more codes. I tell them I do not have any more and that the one I sent to them was redeemed. They tell me they never got it and to send another one to a different email address, to which I tell them no, and if they are so desperate, they can just join the waitlist like everyone else. They continued to harass me about codes until I blocked them.
Cut to today I get a message from someone claiming that a person in their server is going around harassing people with codes under my previous ao3 username (Writer_Child). I had already changed my username for an unrelated reason but if you are getting anything from a person claiming to be "Writer_Child" or claiming to have gotten codes from "Writer_Child", please know they are not me, are not working tokens, and I do not condone their behavior or harassment and I am so sorry to anyone affected.
I feel so stupid for falling for this, I honestly was just trying to be nice. I will be posting this to each of my tumblr accounts that was associated with my previous ao3 title. I am so sorry to anyone connected to this situation. In hindsight I guess it should have been obvious.
If anyone asks for ao3 codes (that you don't personally know), learn from me and don't engage. Anyone looking to get on ao3 can join a waitlist to create an account. Stay safe out there everyone. Block and report.
