As much as i understand from what you have said, it seems you looked at bad example of trade thread.
AS it was example of THREAD and not specific word "leggies", it has nothing to do with word "leggies" per se. So using said word is never said to be "bad" word to use. 
 
 

Gigantamax pokemons are not released yet, as such, users cant get them yet.

I presume you bought pokemon promos.
During claiming those promos you have chance (1/6 chance based on wiki) to get avatar of said promo pokemon
If you want zamazenta crowned avatar you have 2 ways to get it:
buy avatar from pokebay buy zamazenta crowned promos and hope to get avatar during claiming

There is no ingame option to check which pokemon in order you have.
Players the moment they get rare pokemon, go to https://www.pokemon-vortex.com/pokedex and check how many of said pokemon exist in game and that way they know which pokemon they have.

Amount of money you get depends on difference in levels between your pokemon and opponents pokemons, for example, if you win team of lvl 100 pokemons with level 6 pokemon you will get lot more pokedollars compared to beating team of level 100 pokemons with your 6 level 100 pokemons.
 
But there is bit of randomness as well, for example if you beat team of 6 level 100 pokemons with your 1 level 100 pokemon, your reward may be in range of 1500 to 6000 for example (do not remember correct numbers).
 
 

Happiness is added to your pokemon/pokemons moment you see battle end screen with pokemons that took part in battle, exp and pds you earned in battle.
Pokemon may live or not in battle, as long as it took part in battle and is shown in battle end screen it will get 1 - 2 happiness points.

There are one more way to change pokemon name, other then contacting original trainer.
 
That is finding Premium player, as  they can change name of pokemons even if they are not OT of said pokemon. 
Pokemon does not lose its name after it was traded to someone.
 
That is function for premium players.

Did you check spam folder? Sometimes password recovery email may go there. And be 100% sure that is correct email you used when you created account.
 
And
Why does he have to have proof if he is just using Password Recovery and he is asking help with email that does not come.

Yes, you are making request, not asking question. This section of forum is for asking questions about game and stuff of that sort, not to make requests for something to be done that you want. Use general section of forum for that at least.

It tax to reduce amount of money ingame, money sink. So players would work to get money and money would not lose value
