The expanding use of the Internet and personal communication devices has made penny stock scams easier to perpetrate. Though not a scam per se, one notable example is rapper 50 Cent's use of Twitter to cause the price of a penny stock (HNHI) to increase dramatically. 50 Cent had previously bought 30 million shares of the company, and as a result made $8.7 million in profit. Another example of an activity that skirts the borderline between legitimate promotion and hype is the case of LEXG. Described (but perhaps overstated) as "the biggest stock promotion of all time", Lithium Exploration Group's market capitalization soared to over $350 million after an extensive direct mail campaign. The promotion drew upon the legitimate growth in production and use of lithium, while touting Lithium Exploration Group's position within that sector. According to the company's December 31, 2010 form 10-Q (filed within months of the direct mail promotion), LEXG was a lithium company without assets. Its revenues and assets at that time were zero. Subsequently, the company did acquire lithium production/exploration properties, and addressed concerns raised in the press.
