I've noticed a recent tendency against speculative posts. This seems odd, since this was the main reason I joined PF. For instance Arctic Fox asked what seems to be a reasonable question https://www.physicsforums.com/showthread.php?p=621169#post621169 only to be told that it isn't worth discussing. More seriously, users have been banned, where it seems the only reason is that their ideas are non-standard. In particular Caroline Thompson, who tries to highlight the loopholes in experiments demonstrating Bell's inequality. I don't see that this is a reason to be banned. Her posts are accepted by sci.physics.research, and I would expect moderation on PF to be less strict than on SPR. Likewise Eugene Shubert (perfectly innocent) has posts accepted on SPR but has been banned on PF. Is there a good reason for this, or is PF being restricted to 'standard' physics?
