If you're aiming to make newcomers feel welcome and special, I don't think they will feel that way when they see that you just typed basically the exact same message for 9 people before them (+ liked I don't know how many posts), all within a 3 minute time frame, to be honest!
If SS admin really appreciate this, I don't know why they just don't save you the trouble and make a welcome bot.
I mean no disrespect, but dude, you just spammed the forums with 36 one liner posts which add nothing to the discussions that you posted in within a 44 minute time frame. In the past, people were frowned upon for making 10 consecutive posts (even just 3).
Just letting you know that this type of posting behavior is considered annoying by many. And if I were to do this, I would find it to be downright exhausting. (I don't know where you get the energy!) Why exhaust yourself to do something that annoys the community? It's a lose-lose, isn't it?
