I truly appreciate your gesture of good will, however this could create a problem for you where you are doing the work that Plarium should be doing. Frankly, they should have something in-game or in the forums for players to participate in such events.
Relying upon individual players to take on the burden of manually entering data for Plarium, would create an unnecessary burden on players that should just be able to enjoy the game. The game can track how long until my next task refresh, internal messages, various chats, etc..., so they can easily add a mechanism to request inclusion in a game-based bonus.
Another approach for Plarium is to just give the bonus to any account which has logged in within the last 90 days.... That would make things simple for the player base, which is why it will likely never happen. It also does not provide another avenue for Plarium to gather even more personal data on a large portion of their player base. Social media seems to be their favoured platform to gather information rather than using their own platform to let players play and benefit from various promotions.
