We take into consideration few things here:
1) What is someone abuses the merit system with a hacked account. If the original member gets account back, will he get those merits back to spend on quality posts.
2) If someone did this one day after the merit system, it is possible he might be testing. How will such cases be differentiated from abusers.
You have no concerns because of your rank, you as a jr member have nothing regarding merits, you should post when you have something to say, a beggar with a few smerits shouldn't be worried about higher ranks.
After watching the "highest merit replies", I've noticed that a majority are in local Turkish or Russian topics, other languages are non existent or rare. Also, the comments that are given +50 merit, are usually some one liners. Has anyone looked into that or..?
If they are not sources, don't report them. how many hero, legendary members do we have? they might send merits and rank some beggars, it wont last.
