so i just saw this post in the new all feed ... was deleted the moment i wanted to open it for being "off topic".
pls, everyone, be nice to new users. don't just remove their first post for being "off topic". we're already having a problem of not getting enough new users (link)
Your account is five days old. So I don't think your message here carries a lot of weight unfortunately. That post is violating the community rules as well. And the account defended itself to not be a bot when no one accused it of that. So it's probably not a great case to use to start a warm welcome campaign.
Former redditors should be familiar with something like forum rules and how to check them.
