@shibaprasad There is a risk, although the fediverse has the advantage you can chose to be in a more sheltered, more actively moderated place and not exposed to any random insult from barbarians like in twitter.
However, there are yucky people in different instances too, and you might see their content in the "federated" feed.
I was dismayed to see a mirror bot with all the posts from the current US president. Woot.
Still, much nicer and civilized here. I like that communities are smaller and it's easier to get to know someone too.
