Some people were indeed taking advantage of multiple accounts.

One change already implemented is to have all gifts under 10K , because some were sending a Jade to their second verified FB account and taking advantage of the 10x multiplier.

That was also limiting the invites a fair person can send , because with a Jade most of the budget was gone.
And it is better to be able to get several persons invited rather than 2-3.

Second step is to review accounts with similar email but for a digit at the end or coming from the same IPs and disable the distribution.
That is a tad invasive but otherwise the fair minded people that don't resort to this would be affected.
