¿Qué significa 우선 저를 지켜봐 주신 분들께 갑작스럽게 심려 끼쳐 드려서 죄송합니다. 좋아하는 잠가 님 중한 분의 사진을 붙여 거 였는데 전 연령층이보고 있 "는 곳에서 비춰지게되어 송구 스럽습니다. 앞으로는 이런 부분들은 각별히주의하고, 눈쌀 찌푸 리시는 일 없도록 하겠습니다. 장난스러워 보이는 것 같아 다.시 올립니다. 죄송합니다. ?

"First of all, I'm sorry for causing you all so much trouble. I just intended to share a picture(image? drawing?) of one of my favorite writers(painter? photographer?), but the image was very inappropriate for the site that is open to all age. From now on, I will be extra careful not to cause similar issue. I post this because the last apology was not taken seriously. I'm very sorry."

Without the context, my guess is the writer uploaded an inappropriate image to a site, and apologizing for that. It has many grammatical errors, but still written in polite manner.
