There is an another side of the coin. These gamblers might wish to use bestchange as a bridge to withdraw winning into fiat money. If they win a lot (with help from tips and posts from gamblers from gambling board), then the probability they wish to withdraw and enjoy IRL what they achieved is higher. Than bestchange is the best intermediary between crypto and fiat as they offer variety of ways to make an exchange.
Gamblers use bitcoin and crypto. It is correct but the main aim of one signature campaign is having as much exposures as possible to readers. Readers are forum members. People rarely spend their time to read in spam mega threads. I occasionally visit and post on those threads, not much honestly. Because my infrequently visit there, my thinking can be wrong but there are not many high quality posts in spam mega threads.
In this situation, maybe it will be better to limit the amount posts counter in megathreads towards weekly minimum required?
2 to 3, in maximum, I suppose. 10% of weekly post quota in Spam mega thread is enough.
