I may be not the one to talk about this since I have so little experience in the forum. But here I go!
1. Do not ever ask for merits!! Do not try to creep from technical loop holes like "Oh man, Only begging for merits is banned, I did not begged, I just asked!" No It is not okay, Yes I know, sometimes We are pretty desperate when some "valuable posts" (The value of a post totally depends on the individual perspective!! Noobs like us tend to think after posting something that it worths some merit, but actually It is utter bullshit in the eyes of a more experienced user!) do not get rewarded and go deep under in the spamming mega threads where no one notices ever! BUT ASKING FOR MERIT IS STILL NOT OKAY!!!
2. About the negative trust, It can only be removed by the member who assigned it, Therefore contact him. Do not spam him, I thing he would remove the negative trust if he thinks that you have learnt the lesson. I have heard so much about the member ognasty and his attitude towards the forum, He must have done this out of the pure intention of making a spam free forum.
3. I have 3 sMerits left, but since this thread has been created solely in the idea of seeking attention from senior members with sMerits i am not gonna bother to look at your posts history.
Note:
Do not ask for merit, The surprise, Joy you get after seeing some of your posts have been merited is priceless.!!
