Witam szczurekPROS,
They probably thought better safe than sorry, you were right about the obfuscation as now HonzaZ has confirmed, that this is a FP, the obfuscation is "benign".
Still I would leave that shared hosting address as you run particular risks from naughty neighbours there not behaving and there could always come a moment you'd suffer a general IP block. The shared IP address being blacklisted should/could be a "mene tekel ufpharsin" for you to change hoster(sign on the wall מנא, מנא, תקל, ופרסין).
Wszystkiego dobrego,
polonus
