If you read most of the topics giving-away merits, mostly all the participants don't even bother in reading the thread rules; also, I've seen how many even copy-paste whatever they consider hoping to get some merits in return.
We cant ignore the members, who are genuinely read the rules and give their best for getting the merit. We should ban the copy-paster members. We should work in the favour of serious members.
It is not bad for these threads to be difficult to find. Maybe the effort they have to make to find them is, in fact, good.
this is my personal experience, I have found the threads when they have been closed or challenge has been over.
