From the website you linked to:
"Consequently, those who act as salesmen, brokers, dealers or agents of ORGANICO AGRIBUSINESS VENTURES CORPORATION in selling or convincing people to invest in the investment scheme including solicitations or recruitment through the internet may likewise be prosecuted and held criminally liable under Section 28 of the Securities Regulation Code and penalized with a maximum fine of Five Million pesos (P5,000,000.00) or penalty of Twenty One (21) years imprisonment or both pursuant to Section 73 of the SRC."
If that is not bad enough, the next paragraph says:
"Accordingly, those who invite or recruit other people to join or invest in this venture or offer contracts or securities to the public may be held liable or accordingly sanctioned or penalized in accordance with the Supreme Court decision in the case of SEC vs. Oudine Santos (G.R. No. 195542, March 19, 2014)."
In other words, if you listen to a friend's advice, invest in this scheme, and lose money when someone disappears with all the cash, you can sue your friend for the money back. Show them that. Before investing, ask them to sign a paper where they acknowledge reading this and still advising you to invest. Obviously don't invest, but show them the signed document when everything goes downhill.
You might also consider telling them that you have invested, so (a) they leave you alone, (b) they are not angry with you if you are the only one not losing money, and (c) they won't ask you for a loan if you are the only who kept his money. And be aware that when this goes pear shaped, it is you that they will blame.
