I think TheBear did a pretty good job in explaining why you are unable to post consecutively as you have been while the other thread can.
If no one is replying to your thread and you are continuously posting additional content then another, possibly interesting thread is going to get removed from the 1st page. The fact that there is not a lot of conversation in your thread might be a sign that others do not find your thread interesting.
Or it might be a sign that news reportage is not a dialectic/an interactive activity. I read The New York Times, and, at times, find it interesting. Not once have I felt the need to reply. I also read books. Without ever writing "OMG, ur awesom! <3!' to the authors.
People writing comments like "OMG, ur awesom! <3!' would not be conversation, it would be useless garbage. Posts that would indicative of interesting content in a thread would be posts that actually discuss the content of the articles you are posting.
If you have a better way to reliably measure how interesting a thread is then feel free to propose one.
On the other hand if there is some amount of conversation going on in a particular thread then adding additional content via a new post is not going to cause that same damage because there is evidence that others find it interesting based on the amount of conversation in that thread.
We're talking about dozens of consecutive posts, containing nothing but screen captures and links, the very definition of 'spam.' As opposed to my 2 to 4 posts per day of original content.
The posts themselves may be of somewhat low quality, however if the threads they are posted in generate constructive discussion based on those low quality posts then maybe the posts are not as close to "spam" as you claim.
Bear in mind (no pun intended) that this is a
discussion forum, not a
news forum, so topics posted should be discussed.
But most of all, we're talking about fair, evenhanded moderation, impartiality, and keeping one's word.
Global moderators only have the ability to permanently ban someone, and if they want someone to be banned on a temporary basis then they must post in the staff section of the forum requesting a ban. I don't think anyone is going to be permanently banned for bumping multiple times as both of you have been doing without first receiving at least 3 temp bans, although I may be wrong about this.
This means that Grue is most likely not going to be able to ban the OP of your sister's thread. Also when a moderator is working a report, they have three choices, to mark it as "good" (this means they took some kind of action -- for example they deleted a post), mark it as "bad" (this means they took no action as a result of your repot, and to "ignore" the report (this means they took no action on the report, but the report will still show up in other moderator's queues for them to handle if desired). If Grue does not feel strongly enough to take action on your reports then he may simply ignore the report. Moderators are volunteers, not employees and they are not specifically required to take any action they do not wish to take.
You also need to take into consideration that moderation is designed to benefit the community as a whole. As I mentioned before, if a potentially interesting thread (as evidenced as one that is frequently replied to) is removed from the first page of a section because a potentially uninteresting thread (based on the lack of replies to such thread) then it is probably fair to say the community would be harmed by the lack of moderation of multiple updates, while the lack of moderation of an interesting thread would not do the same damage.
Additionally, having multiple unreplied-to posts in a single thread is a sign that the posts you are making may be of low quality and low quality posts are generally removed.
