Looking at the profile, it looks like he is an old member of the forum who received 500 merits through airdrop as per when the merit system was introduced. What he has only earned is 252 merit.

Any user can decide to delete their comments for reasons best known to them; there is no crime for doing so unless there's some shady reason for doing so, like those people who buy accounts or hack accounts; they can decide to delete the old post on the account they have hacked. Apart from that, one can also decide to delete a lot of their posts that they think are no longer relevant. For example, there are thousands of dead threads, and if you think your comments are not up to your standard, you can choose to delete them.
