Please do not add promotional material to Wikipedia, as you did to Arbitrage. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion. Owen× ☎ 13:10, 21 November 2019 (UTC)

[edit]
Please stop your disruptive editing. If you continue to add inappropriate external links to Wikipedia, as you did at Control-Alt-Delete, you may be blocked from editing. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings.
