Crystacune

I read somewhere that you could have as many accs as you want as long as you dont cheat etc. Is this true? I only ask because I dug through my email and found an acc from way back that I hardly played on wondered if it was worth using for a second acc, storage, or w/e. However I obviously dont want to be banned or anything so got to make sure.

Seeking Shadow and/or Shiny Munchlax offering some of my non-shadow legends for them hit me up.
