What are some warning signs for zoom/telegram channels?

I'm desperately trying to find good gay Telegram/Zoom channels but paranoid about joining something illegal unwittingly, as I don't understand all the emojis and group names. Most are PNP which isn't for me but don't care, but many others seem downright off.

I know the blue spiral is a very obvious CP symbol. I see many unicorns and fleur-de-lys, are these dodgy too? Is there anything else to watch out for?
