Help please: one Fediverse app / social network to follow others + upload bulk keywords?

Hi everyone,

Not sure if it’s possible, but would like to know if there is something like this:

1. Can one use just one app / social network to follow the other Fediverse social networks?
2. And if so, does any app / social network allow for bulk loading a list of keywords to use for blocking. (Everything seems to allow to only insert one word at a time….???)

Have had other Fediverse social accounts in the past, but the splintering and keywords issue always becomes a mission. Very surprised that even Twitter / X also only allows one word at a time. Instagram, Facebook and Threads allow for bulk loading with commas, which is also great.

EDIT:

Not sure if this is the right place to ask, but assume some of you might be on other Fedi networks as well? ANY help would be greatly appreciated.

NOTE: using an iPhone, so Android apps won’t work unfortunately. :-(
