Hello,
Is there a way to ignore a user in this forum?
Some forum engine (like vBulletin) allow this.
This option would be useful in some case...

Ok thanks. That's too bad.

I'm "glad" that you did not get it again, so you reply was your usual ... blahh... blahh crap (excuse my French... for goodness sake!)

Syl's request, though
was legit, but...
In addition to the correct answer by Ronny, compare to Laser's usual blahh ... blahh's

As far as I know aside from PM options - vBulletin allows moderators to set certain posts not to be seen by any other users by setting those as "unapproved" - no more then that
Well, it has its negatives:

If some users already answered -  mods has an additional & very annoying work to be done/manage ... otherwise, any given thread can be a complete insanity to read

That is basically reflecting several requests here about removing an account
I was kinda asking about the later aswell, but I do understand the issue -
-  marking posts as ignored / or deleting posts because of the account deletion will make many threads a complete mad-house to read 

Cheers!

Not really, I wasn't poiting anyone.
But I'd prefer to ignore some posts instead of losing my time replying to it (and I'm not talking about what you wrote, I don't even remember, sorry  ^^; )
And I know I shouldn't reply sometimes, that's why it's better for everyone if we can ignore some posts. Mods won't have to enforce rules all the time if we can moderate ourself this way...

edit:
Ah ok, the twitter stuff 
Don't you think this situation would have been better if I hadn't replied?
I request this for my own sanity...
