Does he sound like bad news or genuinely into me?

We’ve been talking online *only* as long distance, have not met in person. I’m 23- Irish, he’s 22- Moroccan. He became very into me, complimenting me endlessly, told me I was his soulmate, we talked non-stop for hours sometimes, I was waking up to good morning messages & got goodnight texts also. He had his moods also though but blamed it on drugs. He told me that he was falling for me, I was developing feelings also but he was rushing things & getting so intense so I blocked him but did let him down first. He then created 2 fake accounts to try to get me back and messaged my sister (who he also does not know) but she blocked him as she was freaked out. I unblocked him to explain my reasoning and he was really upset but he said that talking to me turns him on. I re-blocked him and he created another fake account but I just blocked again.

Opinions?
