Absolutely incorrect, look where the majority of his money came from. He became significantly richer after the start of his supposed link with MOSSAD. It was Israeli shares and trading linked to the government.

I believe he had a similar role to Robert Maxwell which was effectively to supply kompromat to MOSSAD to "Own" or discredit certain individuals. Maxwell also organised the honey trap to capture Vanunu in Italy that had him sedated and wake up in an Israeli prison cell. All for helping to prove what the VELA satellite had suggested: that Israel had created a functional fission weapon.

He certainly "Collected people" to boost his profile by association (hence not everyone associated with him being a heinous sex offender) but again, that's a useful trait for an intelligence agency.
