I don't doubt the veracity of the survey's results shared above, because it's understandable the public gets annoyed with so many gambling ads and sponsorship during the sports matches. Here in my country the championships, clubs and streamings are heavily sponsored by gambling houses. If you watch a soccer match on the television, you will see lots of gambling ads from different betting houses before, during and after the match. Even gamblers get bothered by these intrusive ads.
Ads in an online site are only intrusive when an account is not premium, besides during the match, ads are shown when there is a break or on the part of the screen that is not hindering the view of watchers. In a physical place where the event is happening, banners and ads are put in a place that does not intervene in the game. The only thing I think that the ads are intrusive is on the unofficial telecast/televise of the event where the host is dependent on the ads as a source of income. As a fan,, would they really mind these advertisements and banners? I bet no, one will only mind it if they are into a group of anti-gambling activities.
If there weren't so many of them, I think the results of the survey would be different and people would feel more receptive to gambling ads at the sports scene. Excessive propaganda brings negative consequences for the service or product being promoted, I believe.
I do not think how would an advertisement be excessive propaganda, besides as I stated, I do not think that the survey covers all the football fans, instead it can be set up where the respondents are selected and are not really into gambling. So in my opinion, the survey does not represent the whole of the football fans.
It can really harm the society with too much gambling, but it really depends on the individual itself on how they are going to tackle gambling. There could be that really fall for it and become gambling addicts, ruin their lives and that is the bad effect of this ad as they are somewhat entice to play and play even more.
If there are too much gambling advertisement, the government can implement a counter advertisement like proliferating gambling responsibly reminders to people and state the negative effect of too much gambling. It can be implemented and put together on the gambling ads. After all the government has to say on what kind of ads will be approved.
In some extent I am agreeing with the moderation of gambling ads but I do not think sponsorship should be moderated too because the team needs funding to improve the performance of their players and the sponsorship is one of the sources of fund of the team. Sponsorship is one key factor that improves the performance of the teams and players ( funds for the team training. compensation and many more which gives boost to the player improved performance) thus giving more entertainment to the sports industry.
