My question is, how do I give 50 merit in this simple post? Merit is given to those who post good quality standards, but it is seen that merit is being misused. Merits are being offered to random posts that need to be noted. They are trying to grow new accounts using multiple accounts.
There is no conventional standard for meriting posts because everyone is free to give merit based on personal standards. I have seen posts with more casual words receive a large amount of merits. But I don't think that posts deserve to get such an amount of merits. It is possible that these accounts have a connection or it is also possible that the sender just wants to offload his airdropped merits. Except there is strong proof linking the two accounts, it will be assumed that they have not broken any rule.
