Block??

I have never felt the need to block anyone on this app but there is one person I would honestly rather do without and they are constantly harassing my topic posts. 
  
I have went to block them multiple times but glows little "are you sure you want to block" pop up gives the impression that if I block them, they will still be there and see my posts I just won't see them.
 That would be so anticlimactic in my opinion. It wouldn't solve my issues it would just make me blind to it and the public totally aware of what this person is saying. 
I feel as though this person is 100% aware of what they are saying and how they effect people because their bio basically says "your favourite problematic troll." 
If your sole purpose of using glow is to be "a problematic troll" I feel like your account should be suspended or something. I have tried reporting and glow doesn't do anything but hide their content. It is still there you just need to I unhide it to see it. 
They are on EVERY topic of mine so I don't know if they follow me or what but basically what I'm asking is if I block them will it be the way glow impressions it to be – they're still there I just can't see. 
Or will they not be able to see my topics, profile and comments all together. 
  
  
  
I'm posting anonymously because this person will pop up in my comments and I don't want to deal with them.
