4. NO EFFORTS OF OTHERS:
You acknowledge that any potential increase in the utility or value of the $LMAO token will not come solely from the efforts of others. You have no expectation that others will perform labor or undertake efforts that would result in a profit or increase in value for you.

7. LEGAL JURISDICTION:
This disclaimer and the purchase of the $LMAO token are governed by the laws of the Republic of Malta.
 
8. INDEPENDENT LEGAL ADVICE:
You acknowledge that you have had the opportunity to seek independent legal advice before purchasing the $LMAO token and that either you have done so or you have voluntarily chosen not to.

You further agree to indemnify, defend, and hold harmless the issuer of the $LMAO token from and against all claims, damages, losses, and expenses (including but not limited to reasonable attorney fees) arising from or related to any promotions, representations, or activities conducted by third-party sellers, promoters, or traders of the $LMAO token. You acknowledge that the issuer is not liable for any statements made or actions taken by such third parties, including but not limited to claims related to the potential profitability of the $LMAO token.
 
13. WAIVER OF CLASS ACTIONS OR ARBITRATION CLAUSE:
You agree to settle any disputes through individual arbitration and waive your right to participate in any class-action lawsuits against the issuer.
 
14. SEVERABILITY:
If any provision of this disclaimer is deemed invalid or unenforceable, the remaining provisions will continue in full force and effect.
