SAMUEL.D.S

you start off as newbie (one dot), member once reaches 10 post (two dots), then advanced member at 30 posts (three dots), hyper poster at 100 posts (four dots), hyper poster is highest rank, and then you can make a custom rank after that. i hope this answers your question  

no, you just need to have OT greninja, and make it 4 hearts, and tomorow until 29 may, u can evolve to ash greninja

no.1 auke1993 already answered
no.2 check this link -->https://ibb.co/pfH9QDB  
no.3 hyper poster is highest rank possible, and it allows you to make custom rank

Hope this answers your questions

you need to get points by battles, catching pokes, and having lots of exp.

dont think so, even if he did get banned, he was still fourth, so yeah

of course u can find another one, but u cant find that fast except if ur lucky

you can read this other post for more info  
 
 

giovani specializes in ground types, so use water types, ground types, and also steel types to counter the nidoking and nidoqueen

you need to go to galar sidequests, stay there, explore and u can find 1 at route 25

um, z-moves are unreleased and just press evolve button to evolve your charizard using stone but u cannot change back once you mega evolve

the encounter rate of a legendary pokemon is very low, so it takes time to find one.
sometimes if you are lucky u might find one but usually you must explore for quite a while to find one, even i dont usually find legendaries so easily. and if you think everytime you find legendary, the percentages of finding another one will get lower, then you are wrong, however everytime you find legendary you must explore quite long again to find another one, and even if you do already explore for long, and dont find a legendary, that means your having a bad luck.
here is link to see which legendaries you can find at which route https://wiki.pokemon-vortex.com/wiki/Locations

i hope this helps

did you finish orange islands, since it is from gen 1, i think that is also needed to unlock the ribbon, i didnt really see mine bc last time i finished all of them in 5 minutes, then checked
 

not sure, its still not open, just check every once a week in clans, or there might news in forums once it is added, so just keep checking.🙂

its random
there are lots of questions that hasn't actually apeared in quiz
so you cannot predict what happens next and if we list it, it will be to long
+there will be no use if you don't know what is the answer
