Ok so you both say tag exclusion is not in high demand yet you also say each week there is a post asking for it. How can both be true?
Also why do you exclude steam? we should not take into account Steam just because it is the biggest and most successful game hosting platform? For sure we can't take the example epic is doing since their only strategy is throwing free shit with their fortnite money and don't improve their storefront in any way.
Also I am saying basic because if you have a tag system yet you can not filter out tags what is the point? 6 years ago they did a fast fix to filter 1 tag, what is so hard to implement that in the site itself?
And you talk about malware protection and account hacking, are the hacked accounts being pulled from their servers or are users just putting poor passwords? Account hacking is not always a site problem and it is usually a user problem
