Hello @Oguzkaya34, thanks for creating this thread. @Flamme1230 has made some valid points which summarises the points I was going to go over. I do understand the frustration that you may feel in this situation, but its important to understand that RNG is the key mechanic in PRO, majority of activities such as hunting, item drops, and sometimes PvP/PvE battles are based on luck; this is not "an easy way out" since its the pure reality.
Moreover, the event of 2 shiny Beldums in a day is extremely low, and this cannot be used to accuse developers picking certain players and giving them unfair advantages. In the 10 years of PRO being out for players to play, only a handful of these events occured, this goes the same with the hunting part you have mentioned; sometimes the RNG will not be on your side, this does not mean you are being punished. There is nothing that can be done to boost encounters as this is the mechanics of the game. Developers have massive amount of duties to cover everyday; from working on the game to real life responsibilities, they do not have time to boost player's account
Forums bans or any type of ban does not and will never affect a player's RNG in the game, they are two completely different things. This could be a psychological effect making you feel treated unfarily.
If you do feel there is a bug you can report it, make sure you have enough evidences and drop them into Bug Resolution and a Staff member will have a look at it.
