People really somewhat bash you and saying not good words on you because people want to drag you down and we don't know why, that is why it is better to check really that you ain't getting addicted to it like they arent saying the truth because sometimes if you get mad at them you just makes things worst meaning they are saying true as if it is not true then why are you angry, as long as you know that you are not an addict lets say you are not playing on daily basis or having an unctrolable urge on gambling then you are not addict to and you just say to them that if you are an addict to gambling then you should have those things that you have now as for sure you'll selling it because you want to gamble.
There are many people out there that enjoy trying to bring someone down and they will use anything they may know about you in order to do so, this is simply their nature and they may not even realize what they are doing, so when you encounter someone like that there is no point in engaging them as that is exactly what they want.
It is better to simply ignore them and if they try to confront you about it you just tell them that is none of their business, in my experience this will irritate them to the extreme and will demonstrate to anyone who cares about watching this that they were just looking for a fight with you and then they will ignore anything they said about you.
