Recently now a days , You must have gotten a message from Angel Bot or Celestial Bot saying that you have won a giveaway in a server mostly seducing type and then you need to join that server to receive your reward . Then that server will tell you to join more 5 servers and so on . You are trapped . Also you can be messaged like someone said you cute in this server join to find out whom etc etc like this . These bots are totally scam . You have to be careful . It will also ask you to add this to your server to grow your server but do not do this . If you add this to your server it will target your servers members to join those servers . Please do not use any of these bots . Thanks . Some Images :
