hi all

:local newProfile "slowProfile";

:local userStr [:tostr $user];
 
:local bytes [/ip hotspot user get [find name="$userStr"] bytes-out];
:local profile [/ip hotspot user get [find name="$userStr"] profile];

:if ($bytes > $maxBytes) do={
  :if ($profile != $newProfile) do={
      /log info "[DOWNLOAD LIMIT] - $userStr has exceeded $maxBytes bytes downloaded, changing profile";
      /ip hotspot user set [find name="$userStr"] profile="$newProfile"
