Let me tell you a story.
Once upon a time, I was having a very hard time dealing with family deaths. They happened months apart, but within the same year, my grandparents. I was in college full time, taking care of two of those grandparents (and then just one of them), was working two jobs (three if you count Rescreatu) and was also busily being a mother.
Things got to me. I shut everything down online to keep my head clear. Life got busy, but all I wanted to do was hide in a hole and cry for days on end.
I left Rescreatu, even, seeking help I did not find from friends, family, anyone... even professionals who did not actually help. They managed to make me feel worse because I felt bad about something. I was alone. I was adrift. I was, to be honest, in very bad shape mentally.
It took a while, but I managed to start feeling better. I found self-help books. I even graduated from college, though not a single person realized I'd made it except my own kids.
Friends I had on facebook kept telling me to come back. I kept refusing. They finally left me alone, but still talked about it.
Years later, I was feeling good again, but I was having physical health issues after having a mini-stroke caused by medication I was put on, and arthritis. Friends still talked to me about Rescreatu, so I popped in to take a peek because I was curious. I saw my pets and realized I'd missed them. I saw my friends, who were excited to see me back. I started crying because I felt like I came home.
I was gone five years, but Rescreatu was still "home." And because I did not have to start over, and because some people returned pets to me that I'd given them when I left... I stayed.
Because I was home. And it felt amazing to be back.
I didn't have to start over. Everything I'd worked for was here still. It was great!
Does Rescreatu need work? Yes, it does. But one thing I always hated was the name market. One name can mean things to many. A birthstone, a favorite rock, a name sent to a person as a mockery because of a difference of Opinions that ended up staying on the profile with a pet page filled with quotes. To be fully honest, it isn't how many you have, it is what you do with it.
Clear the named from permanently banned accounts, yes. I'd even support clearing names from inactive accounts after a few years. But you don't know what is going on with a person when they leave. Give them time. They might be back. They might also find out Rescreatu is home.
As for items going for auction, no. Leaving them on those accounts or deleting them just raises the value of the rest.
