What 빬 means
It has no fixed meaning by itself. 빬 is a Hangul syllable block made from three letters, called jamo: ㅃ, ㅏ and ㄽ. The last is a final cluster written with ㄹ + ㅅ. The Korean word around the block supplies its meaning.
Hangul was designed for Korean, whose sounds did not fit Chinese characters well, and to make reading and writing easier to learn. The first record of its creation is dated 1443; Hunminjeongeum explained the letters and how to assemble syllables in 1446.
Hangul first appeared alongside Hanja, Chinese characters used in Korean writing, and later became the ordinary script for Korean. That is a historical connection, not a claim that 빬 copies a Hanja character: Hangul offered a way to write Korean speech.
What does it mean if someone sends it?
Read it as a Korean text fragment, not a complete reply. One block cannot tell you the word, tone or intent; ask for the surrounding word or sentence.
Neutral as a spelling unit; opaque as a one-block message.
Don't treat one block as a reply; ask for the surrounding Korean text.

2Why does 빬 look different?
It can. Hangul fonts resize and reposition letters to fit each syllable block, so the same block can look tighter in one font. The font changes the drawing, not the character.
How is ㄽ pronounced?
At a syllable end or before a consonant, ㄽ is pronounced as ㄹ, roughly like an l without a following vowel. Before a vowel, ㅅ can carry into the next syllable.
