It could be that the moderators don't agree with your report so they don't handle it. The question is, why don't you send a PM to the topic creator and ask him to lock the topic so that what you're worried about doesn't happen?
I told him in the thread that he lock it, but at this point I don't care anymore. If the moderators want to have Meta full of rubbish, that's up to them, and I'm not just saying that because of that thread.
Shouldn't it be reporting the low qualities replies rather than reporting to have the entire thread locked. Obviously the mods will not go hard locking threads every other time as Theymos tends to encourage some freedom of speech as much as possible.
Since you haven't read the second comment of this thread, I'll quote it for you:
1- If the comment is reportable, for off-topic, low value or whatever, it has to be reported, it is not the subject of this thread.
Also, why is the Wapfika report now crossed out? Has the context changed?
Again, as you don't read it I'll quote it like this to see if after quoting it you feel like reading instead of looking two comments above:
Wapfika claims that he did read the comment. I don't think so, the way he wrote his post, but I'll give him the benefit of the doubt. I will leave the case on the list but crossed out.
