For me, useful ang help thread as an open eye for solution sa new trending topics.
Pero if mayroon nang previous post regarding the same problem, or the issue has been resolved and/or discussed in the forum, considered na yan as SPAM.
In such case, we can simply report that thread naman, for proper action of our moderator(s)
But again, I still promote help threads. Kasi kapag may tutorial na ako about doon, i just simply provide them a link for easy reference, or simply tag someone, na alam ko, na may Tutorial na before.
