RE: Experimentations: What should be done to test the effects of a cause and an effect in any investigation of any kind?

Good evening, a greeting I write to you for the following problem that is happening to me, you had days if I published and I tried to publish and all my publications appear in gray and the level goes down to -7, and I enter my notifications and I receive several mentions from @arcange giving me spam warnings and I have not made those posts and therefore it seems to me that my account is being used by someone else, since I have no relationship with those comments and I need your help to avoid such posts , that you can recommend me to solve this situation.
