The parade may affect locally, but on a general scale, it won't be effective in solving the whole issue. Gambling addiction is complex, regulations are required to prevent and measure it widely. So only by judging based on a single unknown video, the effectiveness certainly can't be measured precisely.
Not sure if this will take effect to the whole world issue but yeah locally there is significant effect , though it may be differently from someone who might quit while others might get interest.
but indeed that surely the parade will effect the whole country adnd gambling may become in the news for couple of weeks.
When I said on the general scale, I did not mean the whole world. What I mean is still within the local context, but specifically, the issue is on the general scale. As I said, gambling addiction is a complex issue, and it is seldom can be significantly affected by such simple acts alone. The tweet itself did not get media attention, nevertheless, it become a viral tweet and spark some discussion and debate. That's all.
