Omegle codes?

Are there certain codes or code words for Omegle so that you are connected to specific groups of people and not to random people (or perverts) as is so often the case?

There are these so-called interests. You can enter various interests in this field, such as conversation/chat/etc. But also things like Snapchat/Instagram/YouTube or whatever you want.

I've already listed various interests there, but I'm not finding people with whom I can have a reasonable conversation.

So my question is, are there certain code words that you can enter to chat with certain people?
