So, this is enough to save us from this hassle, but if it's not the default setting, then members should uncheck the tick mark from "Allow newbies to send you PMs" unless you understand the risks. And if you see someone is sending you unsolicited PMs, then simply use the "Report to admin button that will get them banned.
Good suggestion. Every user should have this setting disabled so that they don't receive PMs from newbies.
I've been noticing lately, that the amount of scams are on a rise, especially during the times when the cryptocurrency market is doing pretty well and Bitcoin along with other cryptocurrencies are going high. For some reason, these scammers become more active during these times, maybe because they want to make as much money as possible during such times and use it in the market or whatever, but I just observed this.
Besides such scams, when there is a bull run, we can also find a bunch of scams in the market, in the form of projects that try their best to gain as much hype as possible so that they can get a good number of investors and then they rug pull by selling the tokens in their possession and run away with the money, leaving investors in awe.
