I respect your gladness here, but I like to learn what were the posts of @Sithara007 made you feel as shitposter due to spamming. Could you link to 5 posts or at least 3 posts with some explanation to justify their level of spam. I am just asking for learning purposes. Hope you find time for it.
(This is not limited to @Rikafip but anyone could do and @nutildah would be the most right person to give some samples which led them to sigban).
I just read their posts where I found simple yet very good English and good engagement with discussion still bursting posts posts could be a reason which also might have led for shorter ban among so far list of sigbanned.
Tell me whose alt I am without telling me whose alt I am.

You could make this post from the affected account, there would be no consequences for that since anyone is allowed to appeal for a ban they have received.
Anyway, I had a look at the post history of
Sithara007, and I'm surprised to see that almost 95% or more of the posts only consist of strictly 4 lines. I know that one cannot gauge the quality of a post based on its length, but you can't just follow a pattern and do all your posts that way. You can't convince me that a person cannot have more points about any topic that could make them write more than four lines at least a few times a day. Look at this post:
IMO, Infantino had few choices. If he had stood his ground, then retarded Trump could ruin the entire tournament. Anyway, sport is no longer a sport. It has become business. I am glad that at least in association football the fans are not staying silent and are raising their voice. In cricket, the ICC is coming up with such retarded moves, that it is now difficult to separate satire from news. BTW, as I mentioned in one of the previous posts, I am looking forward to the expansion of the 2030 FIFA World Cup to 64 teams. I believe that it will be a great decision, which will make sure that every nook and corner of the world is represented in the tournament.
Focus on the bolded part. What does that even mean? "sport is no longer a sport." = makes no sense. One should at least explain what they are trying to say properly.
I wonder how a campaign can keep paying someone for making posts with such a pattern. I'm pretty sure that even among a bunch of spammers, there can be better posters than this.
