AFAIK there is a rule that it is not allowed to bump your own post more than 1x a day. Just a suggestion if there are many sports to bet in the same day, its better for you to make it in one post only you can use "[ hr ]" to separate all the matches. And if you want to update or remind your reader you can just edit the post.
Just my 2 cents.
AFAIK that rule doesn't exit and we like to update our users by the most relevant way.
There are in fact some rules like
this one that majority of bookmakers fail to comply (nitrogen, directbet, cloudbet, etc..).
On BetBTC we only use this thread, following the established forum rules.
Have a great weekend
