I posted this in your other thread about the signature campaign overview thread and when you ignored it and continued to post stupid shit there I sent it to you via PM which you likely also ignored considering I got no response and you continued to post off topic.
Posts about the moderation of the forum are off topic unless they are in meta. Threads about the moderation of the forum are misfiled unless they are in meta.
If you wanted to claim that a moderator was deleting/editing posts in an effort to scam then you could post in scam accusations, and this would be the only exception to the above rule.
The thread you created in service discussion will likely be moved to meta. The 2nd post about the moderation of the forum you posted in the overview of signature campaign threads will likely be deleted by a moderator.
To directly answer your question, you cannot know who deleted your posts as the system is directly setup to prevent that to prevent harassment of the moderators. The reason any post would get deleted would be that it broke some rule of the forum, if you want a more specific reason then that then you would need to create a thread here (in meta)
I think this answers both the specific question of this topic and answers the 'root cause' question as to why you created the topic
Yes, thank you quickseller, as you pointed out, you've presented this reply to me several times and via several channels. I thank you for your opinion. But I think you're going a bit too far if you say I "continued to post stupid shit". For one thing, nothing I've posted in the overview thread has been allowed to last more than a minute or two so I don't see how you'd have any idea whether what I'm posting is "stupid shit". I'm sorry that I didn't acknowledge you sooner. I hope you'll back off a bit now.
@hillarious: One reason not to delete it would be to show me that I'm not on some kind of unofficial thread ban from miche??'s thread. Nothing I've posted has been allowed to stand in that thread for over two weeks. Everything I have tried to post in that thread has either been relevant to the sig ad campaigns or the companies involved or to these shenanigans regarding having my posts deleted. The post was intended as a "dudes, am I just not allowed to post anything in here?" test and the answer seems to be "that's right".
I guess I can keep on trying to post relevant things in there but we'll see if they all just go to the trash bin (which started happening when I started criticising ocupy[sic] coin in there a couple of weeks ago).
