Since I am not sure if this is allowed or not in the forum, let me ask in this thread: Is it allowed for a merit source to send a lot of merits to announcement threads for coins for which he is the bounty manager and translator of the announcements?
This is certainly a conflict of interest if he is managing bounty campaigns for the project he is giving merit to.
I don't think this is a huge issue if he is only providing translation services to the project as the amounts in question are much smaller, as are the number of people qualified to perform said services.
From what I can tell, this is only an issue for one of the posts he gave merit to (unless I am missing something on the other you linked).
I think this can be remediated by allowing him to use his sMerit that is not part of his "source" sMerit to "pay for" the post in question.
It might be a good idea to allow for merit sources to specify if they are sending merit from their "source sMerit" or that is the result of the merit they received via their posts from others. As it stands now, merit sources must first spend all of their "source sMerit" and once that is gone, they will spend sMerit they have as a result of the merit they received from others. This would allow merit sources to avoid the appearance of having a conflict of interest when they give merit to these types of posts (or if they wanted to sell merit that is not "source sMerit").
