Probably. But to circumvent the long established practice that members cannot block the administrator, you can apply for most favoured member status. But be aware, this is unusually granted only to members of at least five years standing. In the meantime, hang in there wingnut.
Remember: Coughs and sneezes spread diseases
When Neal (Of Blessed Memory) owned SGT he maintained two accounts, one as Administrator that we could not block, and one as ordinary member where he posted his views and everyone was free to block. I well recall the vitriol Neal would pour on Smiles when Smiles had the temerity to disagree with Neal’s policies and practices as owner.
For the life of me wingnut, I can't understand why you would want to block Moses, even if you could.
I mean, it isn't like you've ever engaged with him on the board or commented on any of his posts you disagreed with.
If you don't want to read his posts, just skip over them. I know it's not the same as putting someone on "ignore" as you can still see the post.
But it is the obvious solution to your "problem."
Disregarding the other 5~6 handles.
Actually, better still, the member concerned could start his own blog and turn off the comments.
Then there will be no bullying at all.
He could even post a link to it here.
Thanks to the ignore feature, many members wouldn't see such link, unless quoted by someone else, as above. So even less chance of bullying.
