My podcast is rejected

Although the four-letter word which appears in your title and descriptions has been censored by the substitution of asterisks for two of the letters, your image still contains the word complete: and in any case Apple don't allow 'self-censorship' of forbidden words. Even though your 'itunes:explicit' tag is set to 'yes', so that strong language may be allowed in actual episodes, it's not allowed in titles or descriptions (or the image) because anyone coming to your podcast would see them immediately, even though they would be warned of the actual content. You need to think of a way round this while not using language like that, I'm afraid.

No: as I understand it, it's not allowed to use the obviously forbidden words even if you censor them in the way you have - it's still quite obvious what the word is, and though neither nor I would be offended there are many people who would be. You are going to have to find an alternative word which won't cause problems. And I see one of your episodes uses a self-censored version of what is tactfully known as the 'n-word' and I would have thought that was a complete no-no.
