I think they may, but it wont be safe.
Avakin gives you xp for completing certain task such as sending message or feeding petkin etc. Simply putting, this tool basically performs those task in background (not actually performing manipulating stacks and all to convince the system that those tasks are being done). That is how we get those XP's. That is why those tools are clean and safe. And that is the reason why it gives us limited XP's.
So unlimited xp, higher chance of getting caught , higher chance of getting banned or Limited but safe . Which one we prefer?
